What Causes Leg And Thigh Pain With Numbness?

years ago playing sports I hurt my neck. Now I have a knot in the back of my neck. at night I wake up at least once with a feeling of bee stings in my right thigh. lately have lost feelings in both legs. When I walk or stand for a shot time my whole leg feels like it is being stung by killer bees. Sit for 5 minutes and can continue what is causing this
