This is the second time I have cycled and I have never noticed this before. I am not sure if this is normal or I screwed up. I've heard from friends before to make sure you get all of the air out of the needle before you stick yourself before and I thought I was pretty careful but now am second guessing myself. On my ass it feels like I have a tumor or something where I inkected, is this something that happens sometimes and shouldnt worry about or what? Should I just wait it out and hope it gos away? If anyone knows anything about this I would appreciate a little insight. I know it sounds a little funny but its a serious question thanks.
