1. BPPV (Benigh Paroxysmal Positional Vertigo
) is a distinct possibility as you have a history of waking up with vertigo and a history of skin diving the previous day. Your vertigo is severe, short lasting and occurs on change of position.
2. Get your hearing tested by PTA (Pure Tone Audiometry
) and middle ear pressure checked by Impedance Audiometry (I/A).
3. Get your ears examined to rule out infection. There are many other causes of vertigo which can be ruled out. Mild inner ear infection
is a possibility after skin diving and should settle quickly.
4. If it is BPPV, medication is of no use and particle re-positioning maneuvers are required.
