gave a friend of mine his injection the other day, i did once cc of sust/eq mix in his left shoulder, then 1 in his right, and about 15 seconds after i did his right shoulder he goes i feel kinda dizzy and i go are you ok and he goes yah im ok and as he is saying ya im ok he fell, he just fell, and i went down by him, asked him if he was alright, again he told me he was fine. finally after about 45 seconds i got him to stand and then sit down on our couch, i had my roomate bring him a cold water and about 10 minutes later after i felt he would be ok i let him leave...wtf just happened? i aspirated, no blood, no air bubbles in the mix before i injected, any ideas? i thought maybe some small air bubbles from the eq, or maybe he was just really excited/nervous? any help would be appreciated, im kinda worried and never had this happen before, thanks guys
