so Sunday I injected into my quad for the first time.a Few hours later it really hurt,theb monday started out fine,but at the end of the day I couldn't walk due to pain.Yestarday the it hurt just as bad,but started getting red,but not fiery red just a little red,but right from the point of entry not over where the needle is.Today the pain is almost gone,it is still this blush red right of the point of entry,there is no lump under the red.I injected 1cc of Test Cyp.Is this infection or a pissed off muscle?
