Before being diagnosed with Hyperthyroidism, my ears rang constantly. Kept me awake. My TSH levels were low, which means Hyperthyroid. 1.74 is low but within normal range (depending on the lab that runs the bloodwork).
The ringing in the ears is better, but every time my Endo tweaks the Methimazole dose, the ears start ringing again. Have read that thyroid disease can cause symptoms of tinnitus. I agree, it's not fun:)
I too have tinnitus and low thyroid. There are times that the tinnitus is almost unbearable and it is all I can think about. There are other times that I forget it's there or it reduces in its level and I don't hear it.
I read someone say they stopped their caffeine. I think I am going to try this also. Taking the thyroid medications doesn't seem to help.
You mentioned multivitamins, do they contain caffeine? I am on a weight loss regimen and I am cutting out my bad carbs and exercising. That is only helping me feel better about myself and getting in shape. I don't think it is helping the tinnitus.
From what I have read there is no KNOWN cause for the tinnitus and therefore no known cure. I really don't like having to "live with it" and would like it to go away. It makes a peaceful evening very uncomfortable sometimes.
