@patheflin Hello Pat. You sure have given it your all with visiting 20-plus specialists. Two years is quite a while. I understand how frustrating it is running yourself ragged in search of answers only to find the answers are not what was hoped for, and that there is no cure. I have had internal vibrations, spasms, electrifying nerve pains and much more over the years that there is no cure for. If not for nothing, you are not alone my friend, neither are the other members who have been posting about vibrations/tremors.

Functional Neurological Disorder (FND), along with other disorders and syndromes, like fibromyalgia, neuropathy, migraine, CRPS, nonepileptic spells, chronic fatigue, POTS, post-COVID, etc... are treated at Mayo Clinic's Pain Rehabilitation Center. Here is some info:

This is where I finally went to get a grip and find help with managing my conditions. It really was a life saver for me. Would you ever think about going to a program like this?
