pinning in my glutes, pinning doesn't hurt, its not til the next day, is this soreness or infection or abscess or whatever that word is, I've done everything the way I'm suppose to, straight in, one in the muscle you feel the pin a little more draw to check for blood, release slow, hold blah blah blah, my left glut feels fine slightly sore, my right is sore and somewhat sensitive to the touch, I've pinned in the right 2 times and the left just once, eod pinn, anyone aware this fool>? what do i look for with regards to infection or abscess. seems like my injections on the right are more irritating throughout the whole process3
