Question on office injections?

Thanks for answering Trent.
No I haven't access to the inserts, but I have my origional packet of info from my allergist. It states:

Immunotherapy
How is it done?

* Small diabetic insulin syringes are used to inject commercial allergen extracts.
* Injections are normally given into the loose ("floppy") tissue over the back of the upper arm, half way between the shoulder and elbow.
* Injections are given under the skin ("subcutaneous").
* This is the least painful place to inject allergen, as there are few nerve endings in the skin.
* When given correctly, the injections should be slightly uncomfortable.
* They are not normally painful and are usually well tolerated by adults and teenagers.
* Some doctors may advise you to take an antihistamine a few hours before each injection to reduce the likelihood of local discomfort and other side-effects.

I am a patient receiving allergy injections at a local family practice clinic. (my allergist office is in another town, so I have my syrum sent to the family practice clinic)
Just recently the family practice clinic hired my old high school nurse who has been in nursing for at least 40 yrs. When she gives my allergy shots, she gives then in my deltoid muscle instead of pinching up my skin & giving them in my subcutaneous tissue in the back of the upper arms like most of the others nurses do. My question is, how do I ask her to give my shots correctly & more comfortably with out offending her or starting an argument? She's very old school and probably wouldn't appreciate a nursing student telling her differently.
