Hip bursitis, or inflammation of the bursa sacs of the hip, is the most common cause of hip pain, states MedicineNet. Trochanteric bursitis affects the bursa sacs on the outer hip, which can cause sleep difficulties due to pain from lying on the affected side.
There are two types of bursa sacs of the hip: trochanteric and ischial. When these fluid-filled sacs become irritated and inflamed, usually through overuse, an individual can develop a dull pain that is present when walking, climbing stairs, after prolonged sitting and during sleep, according to MedicineNet. Trauma from fractures and strains also causes hip pain. Pain may radiate to the hip due to pinched nerves in the spine.
Other causes of hip pain that may interfere with sleep include inflammation from arthritis, sprains and other injuries, herniated disks, spinal stenosis and avascular necrosis, explains Mayo Clinic. Osteoarthritis can affect any joint, but it is most commonly diagnosed in the hips, knees, spine and hands.
Trochanteric bursitis is often accompanied by osteoarthritis, notes Healthline. Treatments for hip pain vary depending on the cause of the problem. Doctors recommend resting the affected joint, ice, pain medications and physical therapy. Doctors may also prescribe surgery if conservative treatment fails.
