Big J, why would you want to scare the guy with a ridiculous diagnosis like that, obviously you are retarded, anyone with half a brain knows that raised red itchy bumbs is an early sign of leprosy or permanent erectile dysfunction, most likely both.
Actually Freddy, it sound like a mild surface infection. Use some anti-bacterial ointment or whatever you can find to treat infections. You were most likely not careful with your injection technique or did not clean the area properly. Keep an eye on it, and if it gets real pussy (huh-huh, I don't know if I spelled it right) you may want to go see a DR.
Big Johnson,
I don't really think you're retarded, not clinically anyways, but then again...I'm not qualified to make that determination, so there's a chance you are.
