I have had dizziness for over 3 months since returning from Dominican republic .I soon got Bronchitis and then a sinus cold. I was told I had fluid in my ears and was put on Serc 16 mg x3 . It did nothing Was then sent to ENT who said could be Meniers and put me on sec 24 mg x 3. I thought vertigo in Meniers lasted only a couple days. I have been on this dosage for a week and still have the dizziness. Is there anything else to try or take or advise on what should be done next .
