question: I keep getting random bumps on my arm was just my right arm for a while that would appear randomly and itch, stop itching but red bump would stay for a while then finally leave, has been happening since around Christmas. Now I am getting them on my left arm, my leg and now my hip. Looks like a bite but they appear randomly throughout the day. I don't use any different chemicals or anything. I also have tiny allergic like reaction on my left around since christmas eve, only itches sometimes... Nothing spreads either.
