I injected test e into a vein by mistake. Didn't feel anything much during the time I did it, but I do recall it hurt more than the average needle poke (might have just been in my head tbh).
Anyways, about 1-2 hours later I would cough often. Mostly when I took Deep huge breaths. I would breath in, then cough almost instant before breathing out. That same night I would cough up and spit out in the sink and noticed blood and fizzy looking stuff. I found out it was symptoms of oil embolism. Took about 2-3 days to go away fully.
PS: that night too I did get 2 rapid changes in body temp. One went from super super cold, I mean my body was shivering with clothe and blankets on and only a shower fixed it. Then I passed out to sleep and woke up sweating like no tomorrow. Other than all above, it was not a huge deal. Just more of a inconvenience tbh. Lucky of the draw if u don't aspirate....
