WOW, Im glad I found other people with somewhat the same issue. Im gettin kind of worried, Ive had a hematoma on my left upper outer thigh for almost 10 years now, from a fall off of a moving vehicle. A day or two after the fall the hospital drained it, it was alot and I honestly cant remember how much. There is basically a dent in the middle of it from the draining, but balooned out on both sides of the drain. It hasnt been "painful" in years ofcourse, I basically forget its there sometimes, until I go to sit and accidently sit on it or put pressure on it. I was just wondering if its dangerous to keep going like this, ofcourse if I was rich and had insurance I would have had it taken care of completely by now, but the initial draining was thousands of dollars and money doesnt grow on trees. I know its dumb to let something like this go on for so long but now Im gettin worried as Im gettin older and I dont want it to turn into some kind of aneurysm or anything. It has always had that numb fluid filled feeling and its just a weird feeling to touch it, and Ive noticed throughout the years that when I take antibiotics for something when im sick, the hematoma starts to get all tingly and noticeable.... Should I leave it be or is it really dangerous to my health??
