Yeah.. its just one of those things, that happens to a lot of people who iv drugs.. Its happened to me numerous times in the past, with all different types of drugs, I have IVd.. Just keep some form of gauze, paper towel, etc handy to put on the site after you inject, and make sure it is sterile of course.. I like to use like 4 sheets of toilet paper, that is clean, folded up into a small square, and then add a little ethyl alcohol to the pad, to keep the injection site clean.. Ethyl and isopropyl alcohol are really very different, in how they react to cleaning an IV site.. Iso alcohol, I usually will use first, pre shot, to wipe my arm down, and ethyl alcohol and peroxide, are both decent antiseptics to treat IV sites.. Or if you don't have them, just wash your arm with anti-bacterial soap, and warm-hot water... it will help too.
