What Does A Black Rash On The Upper Arm Indicate?
a few days ago I noticed a small black circular mark on my upper arm. a day or so later it developed into a circular bruise (around 1/2 inch in diameter) with a red interior. it looks like there are 2 or 3 holes in the center of the bruise--like an insect bite, tho I never noticed being bitten.

Hello. You might be having some allergic rashes. Allergy can develop due to several reasons- some foods like egg, fish, pollen grains, animal hair, nylon, terylene clothes. Just try to find out what you are allergic to & avoid it. Try home remedies. Apply coconut oil daily three times a day for one week. If you are not better consult a dermatologist. It can be fungal infection or eczema. Regards- Dr Sanjay Kini
