How Long Can a Haematoma Last?

Mild hematomas and contusions typically heal within about five days. A large hematoma may last weeks to months and as it heals it will change color and slowly shrink in size. Hematoma pain and swelling may be treated with over-the-counter (OTC) pain medications. Aspirin should not be used as it may increase bleeding.

Can a hematoma be permanent?

Any bruise or other hematoma of the skin that increases in size over time could also present a danger. If a clot from a hematoma reenters the bloodstream, it can block an artery, cutting off blood flow to part of the body. Without prompt treatment, this can result in permanent tissue damage.

What if my hematoma doesn't go away?

A hematoma is similar to a bruise or blood clot but, if left untreated, it can damage the tissue and lead to infection. An injury to the nose can rupture blood vessels in and around the septum where there is both bone and cartilage.
