So I followed the quad inject protocol and pinned in the outer upper part of the quad but i had terrible pain for several days. The next time to inject I pinned the upper outer part of the opposite quad and had the same results. Pain for days! Terrible pain like tender to the touch. No redness no heat just pain!!! I was hitting a nerve but in the beginning I just shrugged it off as bad pip. Lol what a idiot. I love pinning my quads so I was determined to find my sweet spot. Wala I found it in the low low outer quad like almost to my hamstring. My right gets minor minor pip. I posted so my fellow eroiders could see the spot(tiny bandaid) and maybe give it a go. Don't go too low or you will inject in between your ham and quad.
