I have a small bump on my lower arm, its been there for about 3-4 monthes, it doesnt hurt, its skin colored, and its not itchy or anything. I seem to be developing another one slightly behind my left ear, I have one on the back of my head also.
They are only about the size of half a pea, and they do not hurt at all, Im just very worried about what they might be.

My mum says not to worry about them, and she's made me an appointment for the doctor to get them checked this week, she also says that all the doctor can do for me is cut them out of my skin, I'm just wondering so that when I go to the doctor I wont be surprised. Thank you for all of your help.
