Today was my 3rd injection of the cycle, and i had gotten some different pins from a vet supply store in my town (22g 1"). I go to draw from the vial and it takes much longer than with the 23g i had been using. I get my 1cc in the pin and go to inject, and it felt like i was trying to inject a brick, the pin didn't just slide in as usual. I finally get in and go to aspirate, well a massive air bubble goes in and i inject anyway not being too concerned about it. Well as i'm injecting something feels wrong and i start to get a little light headed, i finish the injection and then start coughing and coughing. I go outside for some fresh air and i just keep coughing. It subsides after a few minutes.
So what happened:
Did i move the pin into a vein after i aspirated?
Is there a difference between vet pins and human pins?
If i did inject into a vein is my gear wasted?
I'm kinda stressing out about this and i could use some answers!!!
