My right leg aches when falling asleep and often wakes me up at night. It seems to start in my knee and radiate in each direction. I ve never had knee problems. I am female, 56 years old, 5 3, and weigh 150. Do you have any thoughts on how to relieve this pain so that I sleep better. I do sleep with a pillow between my knees and have done so for many, many years after suffering from back problems. I would think that the pillow would provide relief, so I m totally at a loss. I sleep 95% of the time on my left side, but it sure would be nice to change position every once in awhile. Thank you
