Had a bad case of head spinning,
dissorientation and
nausea whilst laying face down, eyes closed having physio on my back. My GP also my AME gave me the close eyes, knees and ankles together test and I was
wobbling all over the place. Diagnosed VN and gave me a course of Betaserc. Worked well.
Haven't had a relapse in more than a year, though can't balance on one leg, either left or right without falling to the right. Maybe you should try
Betaserc 16mg [ betahistine dihydrochloride] for a few weeks.
Hope things improve.
