Howdy,
My old lady is a nurse and she injected me in my left gluteal area. By the next day the pain was almost unbearable, the muscle swoll and then I noticed today that not only that muscle swoll, the lower back muscle swoll also. I know propanate makes you sore, so I would imagine the double dose I did would make me a little more sore, but geez that was bad. I feel better today though. Also if I didn't hit a nerve going in, could injecting 2 cc's maybe put some pressure on a nerve?
