I just started a cycle and its been a few years since i have touched anything. Im not good with this steriod talk so bare with me. Injecting in the back of the arm i believe its called the Brachialis muscle. Swapping arms every 3 days. Injecting 1 cc at a time.No problems til now. Well the fourth shot into this i forgot to massage it in. That day i was fine but when i woke up the next morning i could barely move my arm. It is very painful and tender. Upper arm is Swollen up and you can tell just by looking in the mirror. And there is a red spot about the size of a golf ball around the injection site. And it is warmer to the touch than surronding areas. Any ideas whats wrong? I would hate to go to the hospital for this and this is the still the first day after injection. Im hoping it gets better tomorrow. Thanks.
