Thanks for this insight. My UM Neurologist agrees with you. Here's my story: Sudden onset of symptoms upon awaking of a morning in 2007. Pinpricking and a feeling of walking in sand in both feet accompanied with occasional shooting pains in one foot or both at the same time. Diagnosed: Bilateral idiopathic neuropathy. Used a compounded topical salve for 3 months, followed by Botox injections in both feet. No effect. The following medications have been prescribed and taken as directed: Lyric, Neurontin, Pamelor, and Cymbalta. No effect followed by 16 Acupuncture treatments. Began using CBD from marijuana (20mg/day), periodic shooting pains have subsided, but other symptoms continue and walking has become unsteady. University of Michigan Neurologist suggests that my previous treatment with BCG treatment for bladder cancer may have been the side effect cause. Recently received information from local ‘Regenerative Specialists’ suggesting that the use/injection of stem cells may offer relief. Marketing sounds enticing, and I don't mean to be pejorative, but this marketing comes from two disparate Chiropractic Clinics.
