I have almost same problems as you and my doctor is a MS specialist too. I have definite trigeminal
and occipital neuralgia
(for more than 20 years now) along with being tired, severe vision problems and so on. my mri has come out clean always. And my doctor's advice was to stop stress, cleanse my system, and figure out what worsens my pain.
i quit my job, do not do anything that aggravates my pain, started running, feel good with running most of the time, except during cold weather.
