I Am 66 Years Of Age And Have Been In

I am 66 years of age and have been in perfect health. Last week, my right leg became weak with a prickling sensation on the outside of my right leg starting from the hip to the ankle. If I am not careful, I feel that I can fall down because I feel like my leg will buckle. I have not fallen and it comes and goes. It seems that when I eat the pain or sensation lessens.
