@Minihulk82 I had a similar situation last fall. 25g 5/8” needle in the delt and everything. That swelling and sunburn like redness is cellulitis, which is why the doctor gave antibiotics. Never had any issues that severe with that exact same oil in my glutes, so I assumed it was MCT oil I was reacting to. However, when it didn’t subside, I chalked it up to a dirty injection even though I always use alcohol prep, clean procedures, fresh needles, etc. I had to get a round of IV antibiotics to get rid of it. I tossed that vial in case it wasn’t my error and it was dirty gear.
