ok i posted on here about i thought i had the test flu. now i am wondering. i injected my left shoulder 4 days ago. i'm using prop. it still hurts was swollen but gone down a bit but the skin is a little red. now yesterday i shot my glute. aspirated and got some blood so moved over a bit. not much pain with injection. about 10 hours later i got into bed and felt sore in my glute. i went to rub it and ouch. found a lump about 3/4" long and about 1/2" wide. today it's swollen and pretty sore. no redness yet. going to see the doc tomorrow. just wanted some opinions on this. so am i feeling like crap from the test or is it an infection
