Livestrong.com reports on the causes of hip pain while sleeping and what you can do about it in an interview with Angelie Mascarinas, MD, physiatrist at HSS. 

Hip pain when sleeping often stems from a hip condition or an injury, said Dr. Mascarinas. When that happens, "lying on your side can put pressure on the area and cause stress or discomfort," she added.

Hip bursitis, a condition that happens when the small, fluid-filled sacs that provide cushioning around the joints become inflamed, is among the most common causes of hip pain at night, Dr. Mascarinas said.

In addition, arthritis in your hip joint can make your hip stiff and uncomfortable during the day and cause aching or soreness when you sleep on it, Dr. Mascarinas explained.
