Can anyone help me with what this could be? I have a lump on each arm in the same place - the inner arm near the tricep, about two thirds of the way up from the elbow. They are very hard, deep down and painful to the touch. They are big enough (size of a small grape) that my husband noticed the first one rubbing my arm. I have looked up info on lymph nodes and there do not appear to be any in this location - only in the underarms and at the elbow. I hate to call my doctor AGAIN, at some point she is going to start thinking I am crazy! Thanks!
