This was the 20th time i had injected myself almost always in quad . I knew there was something wrong , i injected my sust. and at some point i coud not get the liquid to go tru the needle . I really pushed hard . Then i slightly pulled back the needle and i coud inject . 5 days later i still feel sore at my thigh and there is a lump . I coud not have injected into fat i inject about 1 inch and i always inject in the same spot . Anyone ???
