Hello! I am currently on levothyroxine 50mcg for some form of hypothyroidism, it does feel a bit Hashimoto-style, although my antibodies are normal. But what makes me wonder alot is this weird internal vibration, which at the same time is a metallic taste/sensation in my mouth/tongue at the same time vibrating in my whole body, including head, brain, legs etc. It feels like electricity, shaking or buzzing, and it makes my vision vibrate also (if I watch blank wall it is like flashing vibration). This indeed feels very weird and makes me wonder what on earth it is! Can this happen from thyroxine?!
Sometime ago I accidentally took a bit extra thyroxine and the metallic taste got worse, so I started to suspect thyroxine. But I might get metallic taste from foods too, and very weird adrenaline surge reactions to certain foods. This sensation also includes a sensation of nervous system being overdrive and hyperactive, and can cause panicky feelings. On top of this I have insomnia from the hyperactivity (which in turn worsens the vibration). I am going to test my thyroid soon, but I think it shows up slightly elevated TSH and normal T4.
Anyone with similiar sensations? Thanks for reading!
