How to keep tabs on swelling after a crash injury

An orthopedic trauma nurse and a physical therapist explain how to spot change and when to get help

Swelling is common after a broken bone, a sprain or surgery. It may sink lower in an arm or leg as the day goes on. What matters is whether it matches the pattern your treating team expected. An orthopedic nurse checks the limb, the dressing and blood flow. A physical therapist helps you move within your limits. Neither one would judge swelling just by how it looks. [1, 2]

Keep a record of how it changes

Write down where the swelling is and when it started. Note whether it gets better with the position or treatment you were given. Compare the pain, color, warmth, feeling and movement in your fingers or toes. If you have a cast or splint, report any new tightness, numbness or tingling. Report pain that keeps building, too. Do not cut or loosen a cast on your own unless your team gave you clear instructions to do so. [1, 2]

Stick to the swelling plan made for your injury

Raising the limb and using a wrapped ice pack are common early steps for a fracture or sprain. Some people have a cast, a surgical cut, changed feeling or poor blood flow. If that’s you, ask where to use them and for how long. A compression wrap should never be so tight that your pain or feeling gets worse. Find out whether compression is right for you before you add it. [1]

Changes that need care right away

Pain that becomes far worse than expected can point to a pressure emergency. Take it most seriously when the limb is also tight and swollen, or you feel new tingling or weakness. Get emergency care. New swelling in one calf or leg, with pain, warmth or redness, can be a blood clot. Have a doctor check it promptly. Sudden shortness of breath or chest pain is an emergency. [2, 3]

Is the swelling not easing as expected? Call your team for a review instead of stopping all movement or pushing through pain. Ask if your limits, exercises and next appointment date still fit what’s going on. Keep a short daily note. Photos can show change when the area is visible. Never put off care to take them. [1, 2]

Things to ask your care team about swelling

  1. How much swelling should I expect with this injury, and for how long?
  2. How should I raise, cool or move this limb?
  3. What kind of change means I should call right away?

Do a quick daily comparison

Check today’s swelling against yesterday’s. Test the feeling and movement past the injured spot, such as in your fingers or toes. Get urgent care for any severe or sudden change. [1, 2, 3]
