Sending you both my good wishes and thoughts. I'm so very sorry to hear things are still so frustrating. As for the "shot" issue...I'm not sure if this could help but I avoid them myself whenever possible. Not a fan of going to the doctor or needles, despite the fact that it is my life's career dream to become one, go figure right? I do know that there are such things as topical anasthetic creams which you (I think) can buy or order.
Anyway you just apply some of the cream for whatever time it tells you before the shot and voila, no pain. The cream is just very cold and eventually makes the place on your body where it was rubbed a little tingly feeling like when your foot as gone to sleep. Topicaine is the name of the one I have heard of. A thought.
Hug and take care,
Mona
