So I was doing a glute injection today of 1.5 ml of test c. Put the needle in. Aspirated. Got the air bubble, no blood, so I started to push on the plunger. After all the oil was in the middle of my chest started to feel slightly tingly and tight, sort of like the feeling when your foot falls "a sleep." Then I got a slight cough for like 15 minutes afterwards. It wasn't an uncontrollable cough (like I have read about on here when you inject into a vein), just a cough every once in awhile. I have injected hundreds of times and never felt anything like this before. Its kinda freaking me out. Is it possible I some how injected into a vein even though I aspirated? When I pulled the needle out of my glute the puncture did not bleed. Am I just being paranoid, or could some oil have gotten into a vien on the way out or something?
