Brad, hoping that the B1 is going to continue giving you relief! I looked up that case report that you mentioned and it is encouraging (https://www.hindawi.com/journals/crinm/2018/3901619/).
Of course, you know that you could set up a welding O2 system in a couple of days. Maybe your current relief will be long-lasting (or permanent), so you can wait to see what your neuro says after you make up with her next week.
