I watched a friend of mine shoot up yesterday and I have a couple of questions . I ve done this before but not often so I m not real experienced . on the subject. I know she had done it the night before about 3 times all in the same general area so it was a little bruised to start with . When she shot up 1. She didn t register. So I m almost positive she didn t even hit the vein BUT she pushed it anyways . And now she has a pretty big bruise on the inside of her left elbow down her forearm and it s swollen and appears pretty painful when she uses that arm . She also said she had some issues with her hand going numb yesterday. Anything that I can tell her to help would be greatly appreciated
