I have fatty lumps under my skin all over my body, but especially in my thighs and arms. I am not a large person and they are visible to the eye. I have had several removed, but there is no way possible to have all of them removed or I would have scars all over. They even have a tendency to ache. I was told they ache because they do have a blood supply.

What causes these and is there some way to help them go away short of surgery?
