Like Dave said....injecting into fat is what's required. If you don't have much fat on your leg and you can "pinch an inch" or so on your abdomen, that might be easier for you. I never once injected into my leg, always my abdomen - kept it in for a 10 second count after pushing the plunger and then removed. If you have fat on your leg and that's where you like it better, up to you as long as it's working for you.
Good luck with this.

It's normal to have the the worst reaction to the first injection. You should inject into fat not muscle. The thighs and stomach are the most common places to do that.
Good luck with tx.

It wasn't because it was your leg was the injection site. SX vary from week to week. I was like you my first was the worst by far. You can look at the directions that come with the shots for more info on injection sites.
