Now and then I get a strange reaction from a shot. After anywhere from around 6 hours to 12 hours after a shot, I'll start feeling a little nauseous and cold. Over 1-3 hours later it will escalate to flu-like symptoms such as joint pain and a general achiness all over and sometimes coughing, with it usually ending with severe chills and cold sweats. It can last from several hours to about half a day. Then the entire next day, I just feel kind of "out of it" and weak in a strange way. Then by a day or two after that, I'm back to normal. The first time it happened was a few years ago, and I think it's only happened with test. It's happened under two different scenarios. First, it almost always happens if I inject 500mg or more of test in one day (especially in one shot)...but it doesn't happen as severely as under the second scenario. I got around that by just spreading out my shots. The second scenario in which it happens is only now and then, usually a glute shot, but a few times it's happened with a delt shot....even with only a single 1ml/250mg shot of test.......almost immediately after the shot (sometimes during the shot) I feel the urge to cough. Sometimes I have a short coughing fit, but then I'm fine.....but then a few hours later, the above mentioned reaction will happen. With the low dose (250mg) shot, it only happens maybe 1 out of every 10 shots....but it's starting to worry me since the last reaction I had was pretty bad as far as the chills and cold sweats went. Anyone know if maybe I'm just hitting a nerve, or it has to do with scar tissue build up, or what?? Is my body "rejecting" the juice or something like that? A friend of mine died in the middle of the night recently without warning from a health problem he had....it had no similarity my situation, but it still has me freaked out a little. Should I worry?? What the f*ck keeps happening to me??
