I like site injections. Put prop. in my chest and there was pain, put it in my calves couldn't walk, did lats yestarday and they hurt too. I tried using b-12 that didn't work. Should I use oil? If so how much to cut it by? Did the pain cut down enough to even bother? Not that I can't take the pain, I like it. Just ****s up my baseball swing and I have three games today.
