Advice Needed: How to get immunotherapy treatment in a rural area where the clinics do not administer the shots?

I have already seen an allergist, and was on ramp up. We had to move, and to my surprise none of the clinics here will administer allergy shots.

There is a speciality clinic that will, but only if you are a patient of their allergist, they won't administer injections unless it came from them. There is a 3y wait-list for their allergist.

This is terrible news. My seasonal allergies are debilitating, they are a disability. In the words of my allergist "You are allergic to the world".

I could administer them at home, my spouse is an MA and knows how to do the subcutaneous shots. However, that's dangerous, and my allergist refuses to allow me to do this.

The alternative would be to just walk into a clinic or ER, get the shots administered by my spouse in the lobby. Wait the 20-30 minutes to ensure no anaphylactic reaction, and go home. And do this till I've ramped. But I get the feeling this won't go over well....

What sort of advice do you have for me on navigating this Lemmy? I was receiving treatment for this condition, and now I can't, which is essentially driving me into depression.
