Shot on Monday morning with some new gear. Got an infection in my delt. It started to get red below the shot area and began getting bigger and hurt like f***. Had to get a shot in the a** and they put me on kelfex. I hope it is not my gear and only my stupid ass. I drew from the vival and used the same needle to shot. I want to shoot again in the other delt and do the right thing. Just hoping it is not the gear.
