Just as the others said, you will NOT be giving yourself shots. In our program we had to give two to another student (as well as get two), and that would be an IM (intramuscular) injection in the deltoid (at the top of your arm, just below the shoulder), and a ID (intradermal) injection on the forearm to simulate the TB injection.
I don't like injections, either. But, to tell you the truth, that first IM injection was harder for me to GIVE than to RECEIVE! I had previously given one SC/SQ (subcutaneous) injection...but it wasn't nearly as bad as the IM one. Maybe because I was being tested on it, and was trying to remember 1000 things...anyway...it really isn't all that bad, and it is just the one time. Our instructor said that if we didn't want to do it we didn't have to, but she wouldn't let us give one and not receive one...if we didn't receive an injection, we failed that skill.
Good luck to you, and remember to do well in school as your good grades will only help you get where you want to go!
