Are any of you currently on or have you ever tried immunotherapy injections?

Hi, are any of you currently on or have you ever tried immunotherapy injections?
Did it work for you? What adverse effects did you own? how long before you notice a difference? And what part of your arm do you take the injections in. Because all my doctors be injecting my in the muscle high up within my shoulder and I would get massive swelling and a late arms for a day or two. The allergy specialist said its intended to be injected in the little fatty area partially way between the elbow and shoulder. He told me to never allow a doctor to inject it any complex up the arm.I got into a big disagreement near a doctor about this today, she insisted she could inject it whereever she want and terminated up smacking her hand down on the desk and clich?? "Whatever!"
So is it worth it? I've been on it for 3 months so far...do I put up beside the next few years of it or quit immediately?
