Hi Stormyr,
Welcome to the NeuroTalk Support Groups.

I'm sorry that I can't really help you except to direct you to a couple of the other forums here where people may be able to make some suggestions.

The symptoms you are experiencing could be caused by a large number of things. Are you taking any medications for any other conditions at present?

I'm wondering if you've seen a Neurologist to help sort it all out or if you've had any blood tests? You mentioned cyst and MRI. Where is the cyst?

I'll post a couple of links to other forums here in case anyone has some advice for you.

Sleep Apnea and Sleep Disorders Forum

Peripheral Neuropathy Forum

I'm sorry I can't really help you but hope you are able to find some answers soon.
