I have been injecting for a few months now and everything has been good. But the last 2 weeks of injecting has been very painfull. I inject in my gluteus, im alternating injection site each time (left cheek, right cheek) and i have been on Test 400 for 4 weeks out of a five week course, and only inject 1ml at a time, twice a week. But the last 4 jabs have resulted in me wakeing up the next morning in pain and my cheek were i injected being very tense nd very very sore... I havent got any redness or rash and the first 2 weeks of injecting were fine and its happening in both cheeks... I dont inject myself i get my mates mum, who is a nurse to do it for me.... Any ideas whats going wrong? Many Thanks
