I am 58 5'3 200lb female. I have small sore BB size knots to appear in my body in various places underneath my skin tissue I have some that have grown to like ping pong ball size and some are like masses of sore tissue throughout my body very tender to the touch especially in my arms, legs in the thigh area, my rib cage, sides and back. My whole body is tender. this has been going on for a long time. I asked a doctor about them he said they where fatty tissue. but is it? Does fatty tissue hurt and continue to grow? I think it began as a teenager I noticed a lump in my right hip socket around 15 years old. I was always very skinny. didn't think much of it then but now I think that may be where it all began. I am concerned. What is going on with my body?
