ok so the prop injections i'm doing are doing weird things. the first time i injected my quad within 8 hours i couldn't bend my leg cause hurt like crazy. now when i inject them ther is no problem. i inject my glutes and they become pretty sore the next day or 2 days later. my shoulders hurt the next day and swell up. i know i should be using b12 with the shots to lessen the pain. going to order some. any other comments or suggestions on this?
