I am facing a peculiar situation wher i am losing my memory. As compared now i cnt remmber the way i cud do before..i have become forgetful. My legs specialy left gets numb very easily, like a 2 min of idle sit turns my left leg numb. I also would like to draw your attention that till last 6 7 years i often used to get leg cramps (the calf part) during my sleep. It used to b very painful forcing me to stand and relax the muscles to reduce the pain. It hapens rare now bt the numbness is regular. Are all these related to my nervous sysytems and how do i go from now to prevent further damage??
