I injected i cc of cyp on wed morning. By friday afternoon it felt like i had a knot under the skin a few inches away from the injection site. Saturday morning showed it as very raised and red, hard and warm to the touch. I got my ass to a doctor, and got some antibiotics. Now it's monday and the knot is still there, is this an abcess then? When draining it, i just get a large syringe and inject into the middle, then withdraw what i can, correct?
