Hey guys, so I'm pinning .67 eod sust 325, been rotating delts only, haven't had any pain or noticeable swelling, redness, nothing. This morning while pinning right delt as I aspirated a bit of a milky off white substance came out, I assumed abscess. How can I tell if it's sterile or septic? Should i be on the safe side and goto er or hope for the best with no redness? Working 12-14 hour days so 4 hours in the er is what im trying to avoid. I pin around 5am before I leave for work and I pulled around 1.5cc out, and skipped my pin today. Any help appreciated.
