I would find yourself a different doctor who will take you seriously. I ended up with an excellent doctor after some who didn't do much at all and was finally diagnosed with Ménière's disease. He was the only one who took a full history of hearing loss, vertigo, tinnitus going back to 'the first time you can remember anything being wrong'. If your only symptom is vertigo it is probably not Meniere's but there are many causes of vertigo. You can do exercises which may help. Just remember, there are doctors who will take you seriously.
