there are lot of medical issues which can occur from tattooing like hiv infection tetanus hepatitis b and c and allergic reactions. nowadays tattooists reduced such risks by following universal precautions working with single use items and sterilizing their equipment after each use. as you mentioned your piercing was done only till the epidermis the infection is highly unlikely (very very less chance) that you will contact any infection. even if the needle was infected it requires contact with body fluids like blood. so you can relax. still i would like to make the following points:- in case of an hiv infection the test takes about 2-3 months to be positive. hence there is no way to find out if you got infected which is again highly unlikely. there is something called post-exposure prophylaxis (pep) given to individuals who have been exposed to the virus and includes three drugs given only under doctor's supervision. you can discuss this with your doctor. if you frequently get a tattoo done make sure your tetanus and hepatitis b vaccines are up-to-date. always have clear knowledge about the infections spread by tattooing like hiv and hepatitis and their mode of spread. take care and stay safe. for further doubts consult a hiv aids specialist online --> <link>
