dirty shot or cotton fever, help me figure this out
Ok so I've been IV'ing oxy for the past couple of months. Once or twice before I've done a shot and then about 30 minutes later I started getting sick and very irritable and thrown up and the whole symptons of cotton fever or a dirty hit. I started shaking uncontrolably, clenching my jaw harder than I've ever clenched it before and I couldn't control any of this. But these symptons usually went away within it a couple of hours.
Yesterday something different happened. I don't know exactly what I did but I prep'd a shot and went ahead and did it. I was fine for a couple hours, laid down and went into a nod, and when I woke up about an hour later I was completely drenched in sweat. My entire bed was wet, and on top of that I had the worst fever and one of the worst headaches I've ever experienced. It was weird tho because I had a high fever but my body felt very cold, and I had the chills. I got really nautious and eventually threw up.
I'm home from college on winter break, and my mom had been sick with some kind of flu, so I thought she had just transferred her sickness to me or something like that. But I wake up this morning feeling a lot better, and basically I feel back to normal now. So my question is what exactly happened? I know there is no way of telling me an exact answer, but any input is greatly appreciated. This wasn't like the earlier incident where I started shaking uncontrollably, so I'm not sure what happened. I just want to be able to prevent this type of thing from happening in the future.
