So uh, been pinning in leg following directions in the kit. The sharp seems mega long, an inch and a half.

I have hit something twice now and it hurt like heck and I yanked it out in reaction to the sudden pain.

I don't think the sharp (being this long) , needs to go all the way in. I read it's inch and a half for bum and 1 inch for leg. However my quad muscles aren't huge so I'm having a hard time getting this right. Am I still in fat layer, am I too far in... I've dealt with bleeding and tenderness multiple times now. Any tips would be greatly appreciated... These come in a kit from my Dr already filled and there isn't a second option for the length of the sharp.

I'm afraid to pin in the bum after I read you can paralyze yourself LOL....

Pls be nice I'm quite aware that I'm doing something wrong.
