A bump or bruise (no open wound) - Children
What it is
Bumps and bruises can be caused by an impact or a fall. The skin isn’t broken, but there is an injury underneath. If the impact wasn’t hard, a small bruise may appear. If the impact was harder, there could be a big bump or some blood under the skin. It could be painful, and possibly swollen, red, or hot, for a few days. Symptoms usually decrease after 3 days.
What you can do at home
What to do
- Keep the injured area elevated, unless:
- The injured body part doesn’t look right (possible fracture) → do not move it;
- The injury is to the neck → do not move the person or do not move yourself;
- You can apply a cold compress or ice to the injured area for 15 to 20 minutes, every two hours, for 48 hours after the impact. This helps reduce both swelling and pain. Do not do this if you have circulatory issues.
- As of the third day, apply heat to the injured area for 20 to 30 minutes, 4 times a day. Do not do this if you have circulatory or coagulation issues, or if you have applied an analgesic gel.
- If you are in pain, you can take acetaminophen (Tylenol) if there are no contraindications. Ask for advice at the pharmacy.
Avoid
- The injured body part doesn’t look right (possible fracture) → do not move it;
- The injury is to the neck → do not move the person or do not move yourself;
- Do not massage the injured area.
