So I've been a recreational user since the 90's. Shot a lot of dope and I have never missed. Last week I got some from a friend and decided to try it out. Clear crystal stuff. I mixed .20 with 20 units of water, put it in, drew back and saw blood and started going for it. I felt a burn so I drew back again, still blood, and finished my shot. Within seconds I had insane pain running down to my finger tips, back up my arm, over my shoulder to my neck and finally to my head where my eye started twitching and I got an instant headache. All while rushing. I was honestly waiting to stroke out. That night I swore off shooting, but last night decided to try it again. It had been a week. No abscess or discoloration of my arm so I figured it was safe. So last night, .15/20 water...check for blood before I go for it. Same as before. Massive pain radiating from my arm to the top of my head, while rushing. This morning there's no bump or discoloration but fuck it hurts. I've seen people say if it burns at all then you missed but I have also seem people say that it could be something in the dope. Anyone had this happen or have any ideas what would cause this? I think I am going to try a booty bump and maybe give shooting up. That was some scary shit
