The best way to sleep is on your side with your knees bent. You may put a pillow under your head to support your neck. You may also put a pillow between your knees.
If you sleep on your back, put pillows under your knees and a small pillow under your lower back. Don't sleep on your stomach unless you put a pillow under your hips.
Use a firm mattress. If your mattress is too soft, use a board of 1/2-inch plywood under the mattress to add support.
