I have lost most of the hearing in my left ear and have had constant vertigo for about two months. my neurologist and ent are stumped. they have me taking 1000mg keppra 2xday, triamterene 37.5mg daily, and meclizine & ondansetron as needed. help?

Wow that's a problem: If both an ENT AND a neurologist have you taking that much medication, for the symptoms you describe, and you've had no improvement, then they must be on the wrong track. Its crazy for me to 2nd guess two specialists who know you but have you tried a course of antibiotics? preferably 2 weeks of Augmentin or cefuroxime? If not, you should. Ask them more questions. There's something missing here.
