I usually pin in what I believe to be my vastus lateralis in my thigh, basically halfway between my hip and knee toward the outer side of it. I use a 23 ga 1.5 pin and rarely feel but a pinch as it goes through the first layer, I rotate each time and have no issues with scaring, and never feel it 5 or 10 min after. Well the other day just for a change of pace I pinned in the vastus medialis, the muscle I believe to be near the knee on the inside of the thigh. It's been 3 days and it still hurts like hell, no swelling or anything just pretty tender. Is this a bad location to pin? Or does it hurt because I've never pinned that muscle? I don't plan on doing it again as it's pointless to when my upper thigh feels no pain ever like this. I know it's not the hugest muscle but it's not like a delt or anything, I only put in 1cc, anyone have any feed back? I'm not worried it's just strange for me. Thanks!
