Falling or hitting something is common (especially among children). A hematoma then appears, bluish in color. But how can we explain this inflammatory reaction? Dr Kierzek, medical director of Doctissimo, lifts the veil on this mystery.
What is a bump?
This soft and painful swelling is caused by a violent impact on a bony area.
“When bumped, the formation of a bump, often called a contusion or hematoma, is usually the result of a rupture of small blood vessels under the skin, causing blood to pool in surrounding tissues. This accumulation of blood can cause swelling and a bump at the site of impact“, assures Dr. Kierzek.
Although this inflammatory reaction is generally benign, it nevertheless deserves to be treated.
To treat said bump, a few simple tips can remedy it:
- Ice : Apply ice immediately after the injury to reduce inflammation. Wrap the ice in a thin cloth to prevent skin burns and apply it for 15 to 20 minutes every hour for the first 24 hours.
- Elevation : If the bump is located on a body part that you can elevate (for example, arm or leg), try to keep it elevated above heart level. This can help reduce swelling.
- Rest : Avoid applying direct pressure to the bump for the first few hours after the injury. Let the area rest.
- Compression: If possible (and appropriate) for the affected area, consider using a compression bandage to help reduce swelling.
- Anti-inflammatories: Avoid nonsteroidal anti-inflammatory drugs (NSAIDs) or aspirin to reduce pain because they may cause bleeding and make the condition worse. Favor paracetamol.
- Observation : Monitor the bump for signs of infection, such as redness, excessive heat, or discharge of pus. If these signs appear, consult.
Should we rub the bump?
Bad idea. “Avoid massaging or pressing directly on the bump, as this may worsen tissue damage and increase inflammation. If the bump is accompanied by other symptoms such as persistent headache, dizziness, nausea or vomiting, seek emergency medical attention“, says Dr. Kierzek.
