Did you try a chiropractor?

My Neuropathy started with some unusual leg heaviness and weakness, worsening until I fell and could no longer walk less than 3 weeks later. I had been admitted to the hospital 2 days before my last step as they were trying to figure it out. After a month in rehab facility, then 5 months of home then outpatient PT and OT, I gained enough strength and balance back to walk with walker, and even unassisted for short distances on flat surfaces. I get as much PT as I can each year to continue strength and balance as the brain is a very tricky thing with change.
A difference that you and I have is that I haven’t had an MRI, but had nerve conduction study/EMG that showed severe axonal sensory loss idiopathic PN. The doctor said there was no need for further tests since that’s what it showed. I have so many similarities with folks on here who have SFN, who say it is diagnosed by a skin biopsy and doesn’t show up in the nerve conduction/EMG tests. Have you had a skin biopsy?
