Years ago, to break up the monotony of just injecting in my butt, I injected into my thigh. I remember hitting a nerve on the first try and then for days after the injection, my thigh feeling like it had a big bruise.
Last week, to give my butt a bit of a rest, I thought that I would try my thigh again. I tried my left thigh, when I got about 1/2 inch deep, I hit something that was very painful and my muscles twitched all over the place. Upon the second try in a location about 1/4 inch away, I didn't have a problem but of course was very wary putting the needle in. My leg felt bruised and hurt for days.
Last night, I tried my right thigh. Same thing, about 1/2 inche in, I hit something that felt like I was being electrocuted and the muscles were really twitching. I moved the needle about 1/4 inch over and it went in. At first, pushing my gear out of the syringe seemed impossible. I just couldn't move it out. Once I got it going, it went smoothly.
What is going on here, am I actually hitting nerves, the bone or am I just hitting very sensitive muscles?
