Be careful with the over the counter vitamin/supplement self treatment. I caused myself a couple of grand in Dr visits and lab work. The 'coctail' I was taking caused heart arrhythmia, so I have dialed it all back to just (2) B12 supplements that I alternate each day.

Unlike many here, I only have PN. For you and others that have other diagnosed illnesses I think it really complicates things. PN alone is elusive enough that almost all neurologist just shrug when it comes to treatment. PN has many masks and go from a transitory state, then seemingly mutate into a whole new symptom overnight.

Anyway, sorry to be a Debbie Downer, but you have your work cut out for you.
