My legs went numb on June 7th, 2016 and started from the bottom of my legs and receded upwards and I used to drop down to my knees, which have proceded to get more and more often, sometimes 3 or 4 times a day but if I lay in bed, it is only once or twice a day, and now I have learned the on coming symptoms and will learn how to control the oncoming episode. I will see how far the numbness goes until I feel like fainting. Had a lumbar operation from the L3-S2 on 12-29-15. Had a CT scan of the brain neck cervix and all showed normal except for arthristis. Dr. is thinking cardiology
