What an ordeal!
Since the transportation cost sounds problematic, I’d suggest considering a switch of pain doctors. The new one ought to be able to start out right where your current one leaves off.
Prayers and best wishes.
The only problem with changing doctors is that this doctor knows my case, they are thorough in making sure my pain is cared for (with the exception of the nurse being stupid). This one knows my issues and is treating them with 3 medications. What if I get a new doctor and they say “Heck no, I’m not giving you that!” I don’t want to change doctors, this one is treating my pain.
