I just found a lump on my left forearm, about an inch above my wrist. It's about 1.5 inches long, oblong, flat on top, and painless. It feels rubbery with a softer spot in the center, where I notice it looks a bit yellow or pale, and I can move it slightly. I'm making an appointment with my doctor, but would be grateful for any insight or impressions. It seemed to appear suddenly...unless I somehow missed it, which is unlikely.
