@bettyg81pain How did it help? Well, I found out that I did not have something of a life-threatening condition. At this time, someone close to me passed away from ALS. He started with numbness, difficulty walking. So, the concern I had is what did I have and what was the cause. Let's face it, there are a lot of things out there way worse than PN and I wanted the best place to give me the best answers. They did tests that no other facility did so I left with no cause for my PN but found out what might help me cope with PN.
