I had to do my right quad 3 days ago, was very nervous but prepared. Used a 25g 1inch needle.
Got it in, no pain at all, aspirate, inject and done! I thought wow, that was the easiest one ever.
This morning, it was time for the left quad. Same preparation and setup. Got maybe 1/2 way in and BAM, hit a nerve. Slowly took it back out, composed myself, took some deep breathes for a couple minutes. Switched needles, went .5 inches further down and it went smooth as well.
However, squatting SUCKED today. It is painful just to bend down lol. After 3 sets it got better, and managed to get great workout.
So I ask you, how was your first time? (Or last lol)
