Welcome @lisa2022, I know it has to be awful having the tremors on top of the occiptal nerve pain and not being able to sleep. You mentioned you have been waiting for a reply from a neurologist you saw at Mayo but no one has called you back. Another thing you might try if you are setup with a Mayo patient portal is to send your neurologist or care team a message and ask for a follow up. Here are the details on how to setup your portal -- https://www.mayoclinichealthsystem.org/hometown-health/featured-topic/connect-to-the-care-you-need-with-patient-online-services.

Have you tried calling your neurologist again to make sure they got your message?
