I had my first ever injection on sunday in my right quad, 2 days later i could barely walk, today is thursday, i can move my leg fully but it's still swollen and its almost like a round sunburn approx. 8 inches long and 6 inches wide. and is hot to the touch, this is shitty considering it was my first injection ever and i followed all sterility guidelines, should i continue to train or see my doctor asap? a few people said not to worry about it but the more i read on cellulitis it seems pretty serious. please give me some feedback.
