I'm in the middle of a cycle right now and did any injection into my tri. I usaully shoot into the long head but today i decided to switch it up and shoot in the head that runs along the outside of the arm. Everything went fine until the very end. as i was shooting the last few drops my arm started to tingle a little bit and there is now a slight dull pain and stiffness. I used a 25g needle, 1cc, my arm is 16.5 inches. i've done two cyles before and never felt this before? Has anyone experieced anything similar?
