What causes rashes on my elbow?
Patient: I have a rash on my left arm near my elbow. Under the rash is muscle that feels very sore. It appears to look bruised, blue almost. It feels as though its hot & burning, doesn t really itch. When I took a picture and zoomed in I could see little blisters. Doctor: Hi,  Perhaps it is shingles. The rash in shingles is red, blistery and associated with symptoms like aching pain and burning. It is usually distributed along a dermatome i.e along the distribution of a spinal nerve. I suggest you to kindly visit a dermatologist in your region for a confirmation of diagnosis.  If it is indeed shingles, you would need oral antivirals like either Acyclovir and Valacyclovir for a week. You would also require an OTC painkiller for symptomatic relief from pain.  Hope I have answered your query.  Let me know if I can assist you further.
