I just did my T shot, and I've been doing them every week for more than 6 months, so I must have done about 30 of them if you count every week from April 4th.
I've always used a 21 gauge needle and I've never had any problems. Never hit a blood vessel, never hit a nerve, never had an obscene amount of pain.
But when I just did it now, as soon as I pushed the needle in, my thigh muscle twitched. The one on the outside of the thigh, that I was injecting into. It was a big twitch too, I could see the entire thigh just kind of ripple, like a spasm. If it hadn't hurt so much I would have thought it was very cool.
I had to keep going though, I didn't want to pull the needle out and change it and try again. My needles come put together with the syringes too, so I don't even know if I can switch needles without wasting the T that was in it.
I'm just wondering what problems you've had while injecting T, and how often you've come across a problem. This is my first problem in almost 7 months of injecting T, and still I think I'm going to feel a little hesitant next time I have to jab myself.
