Me, too. I just found a small lump just below the crease of my right arm, in the middle. No pain. It seems to move around a little, but I have the same thing on my left arm without swelling. I had an enlarged pore on the right arm, which I squeezed. It was red for a few days. Swelling seems to be going down with no more redness. There still is a small lump on the right arm. I also started to swim every day. I'm right handed. Do I have cancer or a thrombosis? Is my condition common?
