I read somewhere on internet that vertigo could be because of some bacteria or infection in your ear. So u can treat it like this, take two garlic cloves, smash it, then take 2, 3 tblsp of mustard oil, heat it and roast the garlic in it. Remove it from heat. Let it get cool. Then put 2/3 drops in your affected ear at night. I did it 4 two nights and I felt pretty good. Well my vertigo is still there but not that annoying. Hopefully it will get cured if I do it continuously.
