Hello, it was great talking to you.
I am an ENT specialist and experienced in dizziness and vertigo.
I will just summarize our conversation for you.
There are many different causes of vertigo.
Basically, the causes are divided into two, Peripheral and Central.
Peripheral causes are causes in the ear, like BPPV, labyrinthitis, vestibular weakness and, Meniere's disease.
Central causes are causes due to other conditions like cerebellar conditions, strokes, etc.
In your case, your symptoms are more characteristic of BPPV rather than Meniere's disease. Meniere's d is characterized by dizziness at all times not much affected by positional movement with fullness of the ear or decreased hearing or pain in ear, etc.
BPPV is characterized by dizziness on movement of head, acute episodes lasting for few minutes which occur on movement of head, getting up from the bed, etc.
Both the diseases are benign. Both can be recurrent.
Prochlorperazine is the mainstay in both, in Meniere's additionally some drugs are used, in BPPV exercises are the most important. Exercises are very important in Meniere's too.
In BPPV one maneouver can be done called Epley's maneover
For now, you should continue the Procholrperazine. Ask your doctor about BPPV and whether it is more likely for you. Also ask about Epley's maneover.
Also do the exercises from the youtube video below, this is very important:
If the dizziness recures, your best approach is that you see an ENT specialist or a specialized Vertigo Clinic. You need a thorough assessment for your vertigo and specialized tests for this, and these are not done by all doctors. Your PCP/Family physician will have to refer you for this.
Things to discuss with your PCP/Family Physician:
Whether it is true vertigo or not (sometimes psychological factors can also present as vertigo)
Whether your clinical tests for vertigo are positive (you should ask about nystagmus, Rhomberg's tes, Unterburger's test)
Whether it is likely to be Central or Peripheral Vertigo
Investigations to be done for Vertigo - you should discuss about ENG/VNG or Videonystagmogram (this is the most important test for vertigo to find the cause of vertigo), Rotating chair Posturography, audiometry tests.
Whether you need referral to a specialized Vertigo clinic for these tests
Medicines to be used for the vertigo
Vertigo rehabilitation exercises
Note down these points or take a printout and discuss with your doctor. This can help you to get a referral to a specialized Vertigo clinic where the cause of your vertigo can be found.
