Hello, As I was going through history it missed too many things like - is he having high blood pressure? Diabetes? kidney infection? etc. Tremors of upper limb or lower limbs or in general of the body.? His age and body weight? Did you try meeting up a neurologist for the same? As tremors are HMF related issues and it definitely needs a brain scan. Has it been done? Tremors can occur due to end number of factors. We need to have a thorough examination - physical as well as diagnostic procedures so we can come to a better conclusion. As EMG and NCV are abnormal there is a definite need for the Scan once as per what it appears. Medical therapy will begin once we get hold of the reports and then exercise therapy to not lose muscle strength. Hope you take the guidance of neuro physician. Hope I have answered your query. Let me know if I can assist you further. Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist
