Goodmorning. I was afraid that your doctor would want to go down to once a month, then pills. Alot of doctors do that not knowing this can really help with PN. Any B12 is better than none. However, knowing what the weekly shots did for me, I would want to continue with weekly if I had a choice. I stayed on the B12 even after I got some relief. I am into my second year with weely injections. Maybe get the research to your doctor, and try to convince him you would like to stay on for weekly. I do take the B vitamines, B Comnplex as well.
Your doctor isn't completely on board with this. Maybe look for a physiatrist, who not only deals with pain, but treats the whole person at a cellular level. I sure hope all works out for you.
As far as self injection goes, believe me, there is nothing to it. I don't like needles at all, but this is a breeze. Compared to having PN, I was willing, as I had hoped for the results I got. Let me know how it turns out with your doctor.
