Hi Dr Went to have some clothes of mine adjusted at the tailor, who marked with pins on my trouser. Whilst removing the trousers after measurements, with the pins still on the clothes, the pin pricked me and left 2 red marks on two spots on my upper bum but i did not bleed.its still red a day after with a slight pain from the prick, I am very worried about HIV transmission as well as hepatitis, what do you advise amd what chances are there that I could get infected? Please help
