hello and welcome .. i am so sorry this is happening. I don't have an answer but wanted to stop by.
Hi! Well... Vertigo as I have had it for several years vefore all this thyroid mess happens for many reasons. The change in climate, having a cold or flu, or just that those tiny crystals in your ears are all over the place. I can sympathize bc I have been where you are many times! I am too on Armour and it has actually gotten better. Not because of the Armour, but because I am leveling out. You might be hypo/hyper. The last time I had sever vertigo, I ended up in the ER with my TSH levels at 20. So, that was due to that.There are exercises you can do to help as well. When the vertigo is bad, focus on one thing. I know its hard, but it can help. Have you thought about going to see someone about exercising your balance? I do and it helps. I am not sure why this vertigo has come into my life.. not sure its the thyroid or just having vertigo as millions do. If you want to talk more.. feel free to message me.
