i used to have problems with my thigh going numb and fall asleep then cramp up if i stood or lay down for a while or in certain positions. i sought out my chiropractor who found my spine was slightly misaligned and causing me to pinch the blood flow to my legs. after 6 weeks of adjustments that went away entirely and hasn't returned! it also had the added benefit of getting rid of my almost daily headaches.
when i sit reclined back or lie down on my back or on my right side my leg goes numb from the hip down and causes cramps. im just asking cuz im tired of just sleeping on my left side all the time.
