Okay, so sometimes when I do heroin. I'm an IV user. I get a very sharp pain in the right side of my head, right above my eye, in between my nose and my temple. It's always in the same spot. This is normally accompanied with nausea. The strange thing is, as soon as I throw up I feel perfectly fine. And I mean the relief is instant. Usually before I even get up from vomiting. It doesn't happen all the time, in fact it's quite rare. I'm curious if anyone else has this happen to them, what causes it, and if there is a way to prevent it from happening. Most of the time it's not that bad and like I said it goes away after I throw up. But sometimes the pain is pretty bad. To the point where I have to make myself vomit to make it go away.
