You look fine: explaining an injury other people cannot see
How to describe hidden symptoms and ask for support without sharing your diagnosis
You got through the crash. Maybe you were checked at the hospital and sent home, or maybe you spent weeks in rehab. The bruises have faded and the stitches are out. Now people tell you that you look great. You nod, even though a trip to the grocery store wore you out yesterday.
Pain, exhaustion, memory slips, a short temper and new fears do not show up in a photo. When others cannot see a problem, they may assume it has gone away. Some people hint that you are making too much of it, and that can sting long after the comment is over.
This guide looks at why hidden symptoms are so often misread and how to trust what you feel. It also offers words for home and work. It explains how health privacy works.
A crash can injure the body in ways no one else can see. A concussion is a form of mild traumatic brain injury (TBI). Its symptoms can include feeling tired with no energy, being bothered by light or noise, feeling foggy, and trouble concentrating [1]. Anxiety, sadness and irritability are on the same list [1]. Whiplash is a neck injury from a sudden movement of the head. About half of people with whiplash have ongoing pain and disability [2].
Other people often expect to see something. In a study from Northern Ireland, researchers interviewed 16 members of the public about brain injury [3]. Most of them did not recognize it as a hidden disability. Most expected some outward sign [3]. Many used negative labels and pictured people with brain injury as aggressive, dependent or unhappy [3].
People who live with hidden symptoms describe what that gap costs them. In a small study published in 2018, five adults with mild to moderate acquired brain injury met as a focus group four times [4]. They said their hidden problems made everyday encounters feel uncertain [4]. They described the extra burden of being misunderstood. They felt their limits got little consideration at work or from health and social services [4]. The researchers noted that the problems were invisible and unpredictable, and that they carried stigma [4].
When doubt comes from professionals
Doubt can come from professionals, too. Researchers in Australia interviewed 27 people who still had neck pain long after a motor vehicle crash [2]. Some described doctors who brushed their pain aside, and many said that dealing with compensation and funding systems made their care harder to sort out [2]. One person recalled being judged all right because they could walk around [2].
The authors pointed out that there is no test that confirms whiplash, so people may feel they have to prove their pain exists [2]. Finding a health professional who took their experience seriously was one of the themes in the interviews [2].
These studies are small. They cannot say how common doubt is. They do show that people with hidden injuries run into it, so you are far from alone if you have.
Symptoms that others often misread
Hidden symptoms tend to get mistaken for a personality problem. The factsheets below were written for people with TBI, though some of the same symptoms can follow other crash injuries.
Fatigue
A TBI Model Systems factsheet describes three kinds of fatigue after a brain injury [5]. Physical fatigue can come from weak muscles. Mental fatigue comes from the extra effort thinking takes after a brain injury. Psychological fatigue goes along with depression or anxiety [5].
The same factsheet calls fatigue one of the most common problems after a TBI and says up to 70 percent of TBI survivors report mental fatigue [5]. To a friend, it can look like you lost interest in them.
Pain
Pain is usually called chronic once it has lasted longer than three months [6]. A factsheet on TBI and chronic pain notes that pain on its own can bring your mood down [6]. Most people living with both TBI and chronic pain report trouble sleeping, and pain can make complex thinking harder [6]. Someone who sees you wince once may never guess you have hurt all day.
Memory and thinking
Trouble with memory is very common in people who have had a moderate or severe TBI [7]. Examples include losing details of a conversation, missing appointments, or knowing exactly who someone is but not being able to find their name [7]. After a concussion, feeling slowed down and having trouble with attention are common too [1]. Other people may take a missed detail as carelessness.
Emotional changes
After a TBI, some people feel anxious in places that never bothered them before [8]. Some feel more anger and irritability. Families may describe a “short fuse” [8]. The person may not notice that they seem angrier [8]. These changes can come from injury to parts of the brain that handle emotion, or from the hard work of coping with the injury [8]. To a coworker, they may look like a bad attitude.
Comparison compiled by Safety Behind the Wheel Foundation
What others may see and what may be going on
| What others may notice | What may be going on | What can help |
|---|---|---|
| You leave early or cancel plans | Fatigue that builds with effort | Shorter visits and plans earlier in the day |
| You ask the same thing twice | Memory or attention problems | Plans sent by text or written down |
| You snap over small things | Irritability, pain or poor sleep | A short quiet break you can take without explaining |
| You avoid busy or loud places | Noise sensitivity or new anxiety | Quieter settings and talking with your care team |
| You seem fine at lunch and drained by dinner | Symptoms that rise and fall | Knowing a good hour does not mean healing is done |

Believing yourself when others doubt you
When people keep questioning you, you may start to question yourself. You might wonder whether you are lazy or weak. A factsheet for people with TBI says plainly that feeling emotionally distressed does not make you weak, and that it is nobody’s fault [8]. Some signs of depression, including fatigue and frustration, are also common after a TBI, so it can be hard to tell what is causing what [8]. That sorting is a job for you and your care team together.
Measure yourself against your own past, and leave other people’s recovery out of it. Someone else’s fast return to work tells you nothing about your own brain and body.
Keep a symptom log
A log turns a vague feeling into something you can point to. An Ontario guideline for adults with concussion suggests using a notebook or diary to plan your activities and write down what you did [9]. It says keeping track may help you notice when fatigue shows up and what sets it off [9]. The same guideline reports that 27.8 percent of people still had fatigue three months after a concussion [9].
A factsheet on TBI and chronic pain suggests tracking pain for two weeks, along with activities that may be related, then bringing that log to your provider [10]. Your log is a way to describe your days clearly. It is not a tool for diagnosing yourself.
Checklist from Safety Behind the Wheel Foundation
- How long and how well you slept the night before.
- Your energy, pain and mood, each rated from 0 to 10, morning and evening.
- What you did, for how long, and where.
- When symptoms went up, and what happened just before.
- What helped, such as a rest break, a quiet room or a snack.
- Any new or worsening symptom to raise with your care team.
Pace your day
The fatigue factsheet suggests stopping an activity before you get tired and building in regular rest breaks or naps [5]. It also suggests doing your hardest tasks early in the day, while you are fresh [5]. The pain factsheet describes pacing as learning to pause before pain starts, so you are not stopping only after it hits [10].
Deciding what to share, and with whom
You do not owe anyone your medical history. A TBI Model Systems factsheet on talking about brain injury suggests giving each person only the information they need. Only what you feel at ease sharing [11]. It recommends short, simple answers [11]. It also suggests asking yourself whether what you share could affect your standing at work, at school or in your relationships [11].
One way to keep control is to talk about function. Function means what you can do, what is hard for you, and what helps. Saying I run out of steam after about an hour of meetings tells a listener more than a diagnosis would. The medical details stay with you.
Different people need different amounts of information. Your partner or closest friend may hear the whole story. Relatives and the coworkers you see every day may only need to know what helps. Acquaintances may need nothing at all.
You can also say no. The same factsheet notes that you can tell people you do not want to talk about your injury [11]. It suggests agreeing on a signal with a friend or family member, so they can help you change the subject or leave [11].
Who protects your health information
HIPAA is a federal health privacy law. Its Privacy Rule controls how health plans and covered health care providers share your health information [12]. Your provider generally cannot give your employer your information without your permission, unless another law requires it [12].
The rule has limits. It does not protect your employment records, even when they contain health details. In most cases it does not apply to what an employer does [12]. Your employer may still request a doctor’s note or other health details in some cases [12]. Examples include sick leave, workers’ compensation, a wellness program or health insurance [12]. The ADA has its own rules about medical information at work, covered below [13].
What to say to family and friends
Family members can misread hidden symptoms too. Imagine a 41 year old passenger who seems cheerful at a family dinner. Her brother never sees her sleep for three hours afterward, so her refusals of later invitations puzzle him.
A few plain sentences can close that gap. Specific requests give people something clear to do. You might ask someone to drive you to physical therapy on Tuesdays, or to keep a visit to one hour.
If anger or irritability has strained a relationship, bring it up when things are calm. The emotion factsheet notes that anger can affect how much support people get from family and friends after a TBI [8]. It adds that medicine and counseling can both ease emotional distress after a TBI [8]. You might say, My temper is shorter since the crash. I am working on it. I am sorry when it lands on you.
Talking with your employer
This section gives general federal information, not legal advice. Rules differ by state and by employer, so check with the Job Accommodation Network (JAN) or a qualified professional about your own situation.
What the law says in general
The Americans with Disabilities Act (ADA) is a federal law that bars job discrimination based on disability. Federal rules against disability discrimination apply to employers with 15 or more employees, and state or local laws may also apply [14].
A reasonable accommodation means adjusting a job, or how the work gets done, so a worker with a disability can do it. You can ask for one in plain English. You do not have to mention the ADA or use the words “reasonable accommodation” [13]. After you ask, the law expects an informal back and forth between you and your employer [13]. There is no official form, but a written request can be useful [15].
How much you may need to share
At work, you may be able to share less than you fear, though usually not nothing. The ADA does not spell out how a worker should disclose a disability [15]. JAN suggests starting with general information about your condition and the limits it causes [15]. Your employer can ask for limited medical documentation to show you are covered by the ADA, and sometimes for your diagnosis [15]. Employers should ask only for information that helps them understand your disability [15].
Guidance from the Equal Employment Opportunity Commission (EEOC) covers what happens when a disability or the need for a change is not obvious. In that case, an employer may ask for reasonable documentation about the disability and your functional limits [13]. Functional limits are the things your condition makes hard, such as reading for long stretches or working in a noisy room. An employer cannot ask for your complete medical records [13]. You can ask your provider for a note that focuses on your limits and the changes that would help.
Coworkers are a separate matter. The EEOC says an employer may not tell coworkers that you have an accommodation [13]. The ADA lets employers share your medical information only in a few limited situations. Telling coworkers is not one of them [13]. You can choose to tell coworkers yourself, as long as no one pressures you to [13].
JAN offers free, confidential help with job accommodations and the ADA [15]. You can call JAN at 1-800-526-7234 [15].
When symptoms change or feelings get heavy
If your symptoms change, or your mood sinks and stays low, tell your care team. Do not wait for your next scheduled visit if something feels very wrong.
Get help right away
Following a blow to the head, these danger signs mean you need emergency care now. Call 911, or have someone take you straight to an emergency department [1]:
- A headache that worsens and does not let up.
- Weakness, numbness, decreased coordination, convulsions or seizures.
- Vomiting again and again.
- Slurred speech or behavior that is unusual for you.
- One pupil larger than the other.
- Confusion, restlessness or agitation, or not knowing people or places.
- Losing consciousness, seeming very drowsy, or no one being able to wake you.
If you have thoughts of harming yourself, or you feel you cannot keep going, you can reach the 988 Suicide and Crisis Lifeline at any hour. Call or text 988, or start a chat at 988lifeline.org [16]. The service costs nothing and never closes [16]. Veterans, service members and their loved ones can press 1 after dialing 988, or send a text to 838255 [16]. For Spanish, dial 988 and press 2 [16]. Call 911 right away if you are in immediate danger.
Help works, and reaching out is a strong step. The TBI Model Systems factsheet urges anyone with thoughts of suicide, or a family member who has them, to get help [8].
Questions to ask your care team
Question checklist from Safety Behind the Wheel Foundation
- Can you write a note for my employer that describes my limits and the changes I need, without extra medical detail?
- Which symptoms should I track in my log, and how would you like me to bring it to you?
- What may be causing my fatigue, and how should I pace my days right now?
- Could my mood or temper changes be linked to my injury, my pain or my sleep?
- What counseling or other support for emotional changes is available to me?
- Which symptoms mean I should call you before my next visit?
Frequently asked questions
Do I have to tell my employer my diagnosis?
Not always. The ADA does not set a time or a way to disclose a disability [15]. JAN suggests starting with general information about your condition and limits, though an employer may ask for limited documentation, and sometimes a diagnosis, to confirm you are covered [15]. An employer cannot ask for your complete medical records [13].
Can my doctor tell my boss about my injury?
In general, no. Under HIPAA, your provider cannot give your employer your health information without your permission unless another law requires it [12]. Your employer can still ask you for a doctor’s note in some cases, such as sick leave or workers’ compensation [12].
What if someone close to me still does not believe me?
You cannot make anyone believe you. In one study, most members of the public who were interviewed expected a brain injury to show, so doubt may come from not knowing better [3]. Spend your energy on the people who listen. In one study of people with ongoing pain after crashes, finding a health professional who took them seriously stood out as a theme [2].
The bottom line
Recommendation from Safety Behind the Wheel Foundation
Fatigue, pain, memory slips and emotional changes after a crash can shape your days long after you look well to others. Other people may not see them. Some may doubt them, but they are real.
You get to decide what to share. Describing what is hard and what helps often works better than naming a diagnosis, and the law limits what your providers can pass on. A symptom log and a few prepared sentences can make those conversations easier. JAN offers free help with the work side.
