How long will a hematoma last and hurt? I've had it for 2 wks. It's on lower leg. Could it be blood clot. No swelling. Just bruised feeling.

LE hematoma. if a skin deep hematoma you can see the " black and blue mark", if in muscle diagnosed by ultrasound. Can take up to a month or so depending on size. There are also bone bruises when the bone marrow gets edema, muscle sprains, and there are clots which can be quite dangerous as part can dislodge &move elsewhere like the lung. Please F/U w/doc/ER today may need sonongram.
