Dear msk101,

The best explanation tht I have come across on the effect of the muscles which attach to the mastoid to dizzines or vertico is that these can induce referred pain into the ear and thus upset the balance mechanism of the ear.

I must admit that my experience has been only on a few patients, so I cannot say if this is common or I just had the few select patients.

As I said, I will look forward to the other replies to this and how your own outcome is on the patient at hand.

Best regards,

Neuromuscular
