man, i have these symptoms after most shots, but it depends on the gear. zephyr is right with the heating pads, i live by them. try taking some benadryl and exercising and massaging it, if its swelling put ice on it. everyone has bad shots man, i promise you'll be ok. abscess are an extreme fear of mine and if you made sure everything was sterile, you're fine. secondly, never fucking take these drugs based on what a buddy says. stay on here, go get some books and learn how to do it right. i cant tell you how many people fuck themselves up by going by what a buddy says, you are doing some heavy and dangerous drugs man, make sure you know what you are doing. next time wipe the tops of the vials with alcohol, your hands and the area of injection. draw THE CORRECT AMOUNT OF OIL into the syringe and heat it using any technique (hot water, blow dryer, space heater...). make sure to aspirate and massage the area after the injection. i really hope you didnt give yourself an abscess.
