2 weeks ago I had the same problem. 2x I pinned test e and it made me sick AF, couldn't move me arms when I pinned delts, and legs when I pinned glutes. I even had selling in both. Well left glute is still swollen from Monday. But it's going down. Rich piana swears when it sWells to put an ice pack on it. I tried and it helped. He says heat helps inflame muscles, which makes sense. Just be smooth and take your time. Warm your gear, hot shower to relax muscles before pining, be sterile, and inject slow.
