Response to the original post. I was the risk officer for a pharmacy chain for 17 years. Vaccine needles damaging nerves and causing shoulder and neck pain are rare but they do happen. I’ve seen one case and the symptoms were similar to your symptoms and resolved with time and physical therapy. There is a vaccine injury foundation that I believe is a quasi governmental effort that does compensate for out of pocket expenses associated with injuries caused by vaccinations. My $0.02; i have nothing to say either way about the vaccines. That’s a personal choice as far as I am concerned.
Thank you very much for your interest and informative post.
I think my exercises in regaining my ability to bring the string back to full draw have pretty much knocked out the effects on my shoulder muscle/nerves.
