Ok, I'll bite. Dr google can give you a very good idea of the symptoms of benign paroxysmal positional vertigo. Why even the
Mayo Clinic gives you pretty much all you need to determine if your dizziness fits that diagnosis
https://www.mayoclinic.org/diseases-...s/syc-20370055
Many other sites will also walk you through the presentation of BPPV.
If your story fits that diagnosis, yes self diagnosis. And you don't have any of the other worrisome accompanying symptoms... I have no problem with you going to you tube and seeing how to do at home Epleys for a few days to see if you get relief.
Every patient does not need an MRI for every symptom. If all you have is BPPV and a couple days of home therapy works... go on with your life without seeing a doctor or having an MRI.
Now, having said that, in our age group a percentage of persons will have unexpected findings on the MRI, up to and including brain tumors.
