As I have Meniere's Disease , I know all about dizziness and Vertigo ! I had to have a stent put in near my heart to increase blood flow to my brain . There is no cure ! But , you can help control it with OTC Meclazine or Dramamine , Ginger capsules and take two Ginkgo Biloba pills a day ! These will help it become a lot less severe ! I used to fall down and crack my head on things and need stitches ! Try these things together and it will lessen the severity of the attacks ! Also have your Doctor give you a referral to a ENT Doctor ! Good luck ! All of these things , you can find at any Drugstore !
Often there's not a cure but Benadryl or Valium may either be taken orally, with a skin patch or given through an IV. If vertigo is caused as a result of a bacterial infection of the middle ear, antibiotics may be administered. If it is caused by an infection or injury to the inner ear there are surgical procedures that may help.
I had it due to a bad sinus infection which I let go too long without antibiotics! Have you had your sinus's checked? (mine went past the congested phase, that's why I thought I was over the infection!) Best of luck to you!
