It's exactly one year since i had vertigo which is very commonly known here in Japan as a symptom of Meniere's w/ tinnitus and hearing difficulty. Had several outpatient i.v. for nausea relief for on and off attacks until i had to be confined for 3 days each time.Hopeless and depressed, gone to Phil for 2nd opinion, and indeed after labs showed low thyroid hormones. Been on Thyradine for almost 4 yrs but Phil doc said i have been given very low dose(75mcg)the reason i have such ear problems.He raised it to 100 and ear problem esp vertigo stopped though tinnitus is constant sound but bearable.But now back to 75 when i had routine check back to Japan for my tests showed almost on the edge of normal meaning going to hyper.Now tinnitus getting worse and afraid of vertigo to attack.Aside from the permanent sound w/c is unnoticeable, another dominant and louder one came depriving me of sleep and peace.Been avoiding salt,caffeine etc.though i can't deny had eaten uncontrollably after i thought i am getting"well" coz i lost pounds and awfully thin so i was making up. Do you think it caused the recurrence? I learned fr one comment here that more sugar intake triggers like salt?(hyperinsulinemia?) I have my appointment w/ my endo come 6/4 will know the blood results.I've been researching and knew a lot from this forum that tinnitus and Meniere has something to do with thyroid problems, but my Jap endo denied it. This time i'll insist it coz of the comments shared here.This Medhelp is really a big HELP. Thanks.
