Okay, I noticed this last night after riding my horse bareback - I doubt that has nothing to do with it, but I strained the muscle which is under the lump - it no longer hurts, but it did for a while and then the lump
appeared. It is about the size of a grape. It is deep under
, and under a vein, from as far as I can see. It is right on my bikini line. It only hurts when I touch it or something else touches it, although I do feel slight pain now when I walk.
