I am experiencing numbness and weakness in left side hand and leg. The other side is totally normal. It was started with numbness in last finger and slowly it is increasing every year. I don't know weather it is Parkinson's or what. I had done so many tests which includes Brain mri- normal (neurologist) NCV- normal (neurology) Spine mri- normal ( neurology) Blood tests Lipid profile, vitamins, hiv and so many Even as per the general physician I don't have diabetes but my vitamin b12- is 149 which can be low and also having cholesterol. I'm 24 years old and my weight is 98kg so is obesity the cause for numbness and weakness or Nutritions ? I even feel so weird due to this condition. Anyone please help me and show me the right way to get cure for this
