I just had an ENG test last friday. My ENT called me and told me that both of my ears were 'weak', he asked me if i had ever had any IV antibiotics or anything, which i havent. I originally went to see him due to an off balance dizziness ive had for almost a year. He said some kind of vestibular thing, but i didnt understand exactly what it was. He equated it to a jet plane having two engines (my ears) and both of the engines were running weakly. My hearing tests and everything were ok, just the dizziness. So he is referring me for 10 weeks of therapy. Does anyone know anything about what i describe? I dont know whether to be happy or sad...apparently this cant be cured, but the therapy can help it....what is this?

Thanks, all....
