What is the hard lump under a bruise?
What is the hard lump under a bruise? The trauma causes tiny blood vessels, called capillaries, to break, and then blood leaks from the vessels into the surrounding tissue. Sometimes, enough bleeding occurs so that a lump also forms (this lump is called a hematoma).
What happens if a hematoma is left untreated?
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.
How does toothpaste help bruises?
Although there is little evidence for this, you'll find that healing bruises is on most lists of random uses for toothpaste. It is believed that toothpaste helps break up the clot and increase blood flow.
