Before i was diagnosed with an underactive thyroid I had episodes of been freezing and shaking all over. It seemed to start in my legs and work its way up my body. The shaking was not like shivering but quite violent shaking. No matter what i did i could not get warm.
Since i started in my medication i can only remember it happening the once and i put that down to me being outside in the cold.
I was wondering if anyone had experienced this as it plays on my mind.
