Hello Carlos @carlitto,

Welcome to Connect. I can understand your frustration trying to know what to do. I have no medical training or background but I do have small fiber peripheral neuropathy. My only symptoms are numbness and a little tingling in my feet and ankles so I don't have to take any pain drugs. Life changes and anxiety can definitely have an impact on a persons health. My doctor also wanted to put me on statins for cholesterol levels but after doing a little research I decided I would try and make better lifestyle choices and eat healthier to lower my numbers. Statins make neuropathy worse and they have a known side effect of inducing neuropathy.

To answer your question on does small fiber neuropathy also cause muscle spasms, there is some information to support it here:

Carlos have you thought about getting a second opinion?

I’m not sure if it is an option for you but if it is, the Mayo Clinic is very good at diagnosing health issues that are difficult to diagnose. If you would like to seek help from Mayo Clinic, you can contact one of their appointment offices. The contact information for Minnesota, Arizona and Florida can be found here:
