Did I hit a nerve?

I just started injecting a couple weeks ago. The first two went great. I did my third on saturday and thought that one also went great but yesterday, two days after the injection I have terrible pain in my thigh. Kept me up most of the night, so I guess I hit a nerve and had a delayed reaction? Hopefully this wont last long, but now I am a little gunshy. I thought I injected roughly around the same place as the others, just in the opposite thigh on the latest shot. I have been doing intermuscular. I have seen some discussing about intermuscular vs subQ. Is there really that much of a difference? Do I lose effectiveness by doing subQ and can I use my same needles for it and inject in my stomach instead?

What size needle are you using? I use a fixed insulin 1/2" 27g which works quite well for IM.

I'm not super experienced, but I suspect that if you hit a nerve you would feel it right away. I've been injecting IM into the thigh for over a year now and once in a blue moon I will hit a nerve, which hurts right away. I usually pull out and re-inject near by and it's fine.

Maybe you got an infection in your leg, which showed up 2 days later? Are you swabbing with alcohol and washing your hands before injection?

I did swab but did not wash my hands. For some reason I did not think that was so important but maybe it was. I might try in the shoulder next time. and I will wash my hands just in case

Many of us do notice a difference in effectiveness, which has not been well documented in the few studies that exist on the topic. Maybe 30-40% of men have worse results with subq if I had to put a number on it. By worse results, I mean any combination of the following: lower serum T for a given dose, higher serum E2 for a given dose, or feeling worse even when serum levels appear similar.

The vast majority of IM injectors do not use quads. There is a higher risk of hitting a nerve than other popular locations and often more PIP. Delts and ventroglutes are the best sites in most people's opinion. I even prefer pinning my lats over quads, which should tell you how far down quads are on the list.

I've never tried the shoulder, but I hear it works OK. Really the thigh for me is pretty good; I might hit a nerve once every few months or so. Feels a little like an electric current, but not super bad. Yes, you do get a bit gun shy after it, just get back on the horse.

Make sure you're injecting NOT into the top of the thigh, but a little bit to the outside of the thigh, maybe 1 1/2" from top dead center towards the right if doing the right leg.

I would switch to a different location. Too many nerves in the thighs. What about shoulders?

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
