I have a couple of I guess I would say red bumps on my back one on my arm. I never really worried about them before cause most of the time I forget they are there. They dont hurt I only know they are there is i look at my back or feel them when I may rub my back. They dont look abnormal. They are red and dont hurt. They are starting to get smaller. I was wondering would that happen if it was a melanoma or would it just get bigger or a different shape. If any one could help me I would appreciate it
