It can go in your leg..... the absorption will be a bit diff but leg is fine. It is a subcutaneous needle so anywhere from 6mm to 12mm depending on what you use. It can go in the following spots: tummy but avoid within 2 inches of belly button, outer thigh, upper outer buttocks, upper outer arm. Arm and leg it will be absorbed more rapidly and wear off quicker...bum and stomach has a more steady absorption rate. the first 8 years or so I was a diabetic i used my legs only without problems then switched to tummy...... now I use a new fangled technology pump and actually have it in the tissue on my back/kidney type area so really as long as you have skin there you can use it!!

you dont really need to pinch the skin but if you find it helps you by all means do it....a trick to relax the nerves etc is to breath out as you are pushing the needle in it forces relaxation and the pain will be less.
