Benefits of Sleeping with a Pillow Between Your Legs
May reduce sciatica pain

Sciatica is an impingement of your sciatica nerve that usually leads to pain in your buttocks and down the back of your leg. Sleeping in positions that cause twisting of your lower back and hips may make sciatica pain worse by further compressing the nerve.
Sleeping with a pillow between your knees may help you reduce compression by keeping your spine aligned.
First time here, haha
