it certainly warrants having a doctor check it out. you could be dealing with a hematoma -- a blood clot in the tissue that could compress a nerve or cause some other problem. (not to be confused with deep venous thrombosis which is something different entirely. ) you can start with a visit to your primary health care provider. he or she may order an x-ray or ct scan of your triceps to see if there's a hematoma hiding in the tissue of your arm. if there is your doctor may wait to see if the body successfully cleans up the excess blood cells. otherwise a minor procedure may be required to remove the knot. usually these types of big bruises heal up with no treatment at all. however given that you're still noticing a lump two months after the injury it doesn't hurt to have it checked out. wishing you well!
i hit my tricep and after 2 months the lump is still there should i be concerned? . i banged it pretty bad in a minor car accident and all the bruising has went away but the lump didn't and is still a little painful.
