Vestibular disorders refer to balance issues.

Nick,

You are doing yourself a disservice by trying to self-diagnose.

A compressed brain stem would cause symptoms far worse than anything you have experienced. You would likely be still hospitalized. It would show up on a routine neurological exam.

An intermittent minor brain stem inflammation or inflammation near the brain stem could cause some autonomic nervous system dysfunctions, such as very slow pulse rate, low blood pressure, inadequate breathing, poor digestion etc. Tingling in various areas of the body could also be a symptom.

What other forum caused this concern?
