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, theyre just there.  Could you tell me what it could be and how to treat them or see the doctor, thanks.  Carolyn
Hi and thanks for the query, Skin rashes as such might not be easy to know their exact causes except one gets a good clinical examination. An image of the rashes coupled with a complete clinical review in more than 90 % of the cases gives the doctor the exact diagnosis. Rather than doing sensible guesses, I strongly suggest you consult your primary care physician for help. Thanks and kind regards, Bain LE, MD.
