ive been banging my head against a brick wall for years trying to get to the bottom of my dizziness and numbness. I saw my GP a couple of months ago who agreed that enough was enough and maybe we should stop blaming it on my thyroid ( or rather lack of it , had RAI 3 years ago ) Ive had blood tests, 24 hr urine test, heart tests and an MRI all of which were clear.My next step is an app with a neurologist next month. Now im wondering if its as simple as the thyroxine making me feel like this ? would it be safe to stop it for a few days to see if the symptoms go ? or should I wait and see what the neurologist says ? thankyou.
