I have pretty good veins, usually, and have never blown or otherwise totally fucked any of them up. I rotate a lot, use small, sharp points, practice good technique, etc.
I did .2 of h last night, then this morning did the rinse of that and a shot of oxy at the same time... used the same vein.
I've noticed, especially with the h, when I shoot into this one vein it BURNS like crazy. It feels like alcohol in my vein until it gets to the top of my arm, and only last for a second. The first time it happened I thought something was way wrong, because it feels so strange and alarming.
I am not missing at all, I feel every bit of my shot there. It just burns. Ideas?
