After having a sinus infection for a week I noticed a blister looking bump on my thumb at the same time I had genitile sores and around the “back door”. Im scared. What is it?
You need to see a doctor who can examine the area and verify whether it is an STD or not. Early treatment is always advisable. A staph infection in the nasal cavity can spread to other parts of the body and cause skin infections but only your doctor can advise your further after doing the necessary tests.
