Hey guys. I took a shot last night at 6pm in my inner leg, now it's noon the next day and the injection site has swollen to the circumference of a tennis ball (or maybe a little smaller). The bump itself is only slightly/moderately elevated though. It is slightly red and it does seem to have a warmness to it. This injection was from an igf shot (please don't move this thread to the peptides section, I won't get many responses at all if you do and I need advise) which was reconstituted with 0.6% acetic acid. It's the first time I've ever injected it. The IGF was from the site sponsor so I'm confident that it's good. How worried should I be that is infected and how long should I wait before going to the doctor? As I mentioned earlier, it's been 18 hours since I took the shot. Thanks guys
