For the past few months I have developed a new symptom on top of my pre-existing health issues.

Right now every time i press down on my teeth or start chewing I feel various parts of my head move. I don't know if it's my veins or parts of the brain itself...

Apart from that , for the past few years I've had...
- On set of sinusitis (had a surgery to correct)
- Candida overgrowth from anti-biotic usage
- Progressive memory/concentration loss.
- The possibility of a major sleep issue involving lack of REM sleep.
- Discovered on an MRI that I have large white-matter brain lesions


I'm wondering if anyone would know what this symptom would be called and/or possible causes.
I've done plenty of lab tests and allergy screens and nothing would match up to this.
I've been taking various supplements and medication to deal with my ailments. I can't seem to find any information on this anywhere.

Thanks.
