Hello. I have a large bruise on the front and side of my right thigh. It happened just over two weeks ago. I did go see a general practitioner but there is a large lump under the skin that is like a big knot of muscle or something. The bruising is healing and it was a bad accident but the lump is so slow to change. I ve been iceing and heat and stretching. Any suggestions besides massage to loosen up the lump?
