In October 2010 I was diagnosed with Hashimotos... The last week now I have been getting severe hand tremors, and dizziness, also makes me feel jittery in my body. Some days I get these burst of energy, and next I will be so tired. My doctor is clueless. Does anyone have these symtoms?? Or maybe give me some clues on what causes this.. I am on Levythyroxine 25 mg.
