I am a 29 year old male. I was previously diagnosed with essential tremor, for which I have been taking Propanolol 160 mg for six years. My current symptoms are constant tingling, soreness, and restlessness of the legs. I get spasms in the legs as well as arms. My right eye goes blurry when it is too hot or if I am in the bath. Also, I have been really sensitive to heat recently, and there is slurring of speech. My right eye also droops sometimes. My legs are weak, and I have balance issues. I have a positive Babinski and Hoffman sign. I would appreciate some advice on what condition this could be.
