Over the last couple of years, everytime I have an injury or knock myself from somthing - say working around the house, hockey, or whatever - I seem to get a permanent hard lump on my bone. I am 40. Any idea what could cause this?
For instance, I bumped my shin on a car door corner 18 months ago, and I have a permanent marble-sized lump there. It didn't seem like that big of a deal at the time.
It does have to do with the healing process of bones. Bones will grow over the affected area (producing a noticeable palitable lump). I have seen this not only with my own bones, but also when my son broke his collarbone last year. The xrays showed the lump over the break and the orthopedic said that's how bones heal and mend themselves.
Hope this helps.
