For about five months I have had a lump under my arm the size of an olive and a lump on my upper thigh, same size. They have no color just tender. My Doctor doesn't know what it is. He said maybe erythema nodosum, yet I looked it up online and the pictures and description don't match what I have by a long shot. I have a biopsy on 7/11, but now I am beginning to to get headaches that I would describe as a migraine. It begins on the right side of my head as a sharp pain that radiates to the whole right side of my head. Also, my pinky, ring and middle finger of my left hand are constanty pins and needles. I am beginning to really freak out. I'm sure none of this is related or big, but my doctor not being able to give me answers is frustrating and scary.
