yesterday i shot heroin in my right arm but missed causing the normal side effects. So i stopped using that arm the next day (still not using that arm) i had a numb tingling feeling in that arm almost a weak tight feeling from my elbow to my hand. Do you think i hit a nerve or what may the cause be?
Hi 120491gjz, Well come to Bluelight!
Well the short answer is, quite possibly! Longer answer, though usually when you hit a nerve while injecting you will know right away because it can be extremely painful (fairly short lived providing you move the pin as soon as you feel the pain.). The pain would be very sharp (no pun intended), it would basically feel like electricity shooting through the area you shot in. It can be quite intense. Sometimes it can be a sharp burning sensation and when you really nail a nerve, in your arm for example, your muscles may twitch a time of two somewhat violently.
If you had no feeling like that at injection, it doesn't mean you didn't hit a nerve, all depends, if your majorly snowed at the time, your brain may just not feel it, but this I would think is fairly rare.
I don't know your IV use history, but if you have a long history of IV use, or intense IV use, and you have collapsed, destroyed, blocked a number of veins in your arm, and you happen to miss again but in a way that caused damage to yet another vein, you could certainly get the feeling you are describing.
More then likely however, you probably shot very close to a nerve could possibly cause local anesthetic like feelings. I have never used heroin so that last statement is more of an educated guess, however, heroin has been known to be cut with local anesthetics such a lidocaine, dimethocaine, rocaine, among others. So it's all possible.
Glad it has since cleared up so it's likely not anything more problematic.
Good luck and please be careful!
