Was doing a quad inject and hit a nerve for the first time. Shit was weird. Felt it once I got about 3/4 of the pin in and my leg jumped, so I pulled back a bit and started injecting. The oil went in fine but when pushing the last bit in, it hit the nerve again and my leg jumped. Feeling a little more pip than usual and I noticed my injection site is lower than I usual go. Just wanted to post up my experience!
