Ive had what looks like a rash on the back of one hand for over 3 months.  It is not itchy or painful but hasnt gone away.  It may be spreading just a little bit...  It looks like the skin is a little raised and reddish but no blisters or anything significant.
Hello, You have a history of chronic rash which does not itch. Such rashes commonly are due to side effects/ reaction to medicines you are taking. You have not mentioned what medicines you are taking. It can be due to allergy, an infection like ringworm or due to too much exposure to the sun. Vitamin B6 deficiency also causes such rashes. Do not keep skin Chat Doctor.  Take care of your hygiene, avoid exposure to the sun. Take vitamin B6 & folic acid supplements. If sexually active, visit a dermatologist. Get physically examined, get STD tests done to rule out contact dermatitis, psoriasis, etc. If test reports are positive you may need antivirals & antibiotics. Hope I have answered your query. Let me know if I can assist you further. Take care
