question: Hi, I have a raised skin rash that is non-itchy that started on my right lower arm about 5mm round.  It appeared about 1 month ago.  It has got larger, now about 2cm in diameter.  There are now other similar spots/rashes starting to appear on my torso and legs.  They do not bother or irritate me in anyway, they're just there.  Could you tell me what it could be and how to treat them or see the doctor, thanks.  Carolyn  :)
