1.Sleep with a pillow between your legs on your side.
If resting flat on your back is too uncomfortable for you, try lying on your side:
-Allow your right or left shoulder, as well as the rest of that side of your body, to make contact with the mattress.
-Lie down with a pillow between your knees.
-Fill up any gaps between your waist and the mattress with a small pillow for further support.
Resist the impulse to sleep on the same side every night, whether you sleep with one or two pillows. Overdoing it might result in muscular imbalance and even scoliosis.
You will not feel any better by sleeping on your side. The key is to put a pillow between your knees. Your hips, pelvis, and spine will be better aligned as a result of the pillow.
