So last thursday I injected 2ml of test E 300 in the left leg and 2ml of tren e 200 in the right leg. Right leg is fine completely, left leg is swollen, cant bend, very tender to touch, throbing pain and running a 101 fever. My question is to go to ER or to wait it out? No this is not my first cycle and yes I have injected in this leg before just fine over the last few cycles.
