Among the causes of hip pain during sleep are tronchanteric bursitis and pressure on the sciatic nerve, according to eMedicineHealth. Other causes include arthritis, bruising and strain from overuse.
Trochanteric bursitis occurs when the bursas, the sacs of fluid that form cushions between the tendons and bones, become inflamed as the result of injury, excessive pressure on the bursa or repetitive movement, explains WebMD. Beyond sleep disruption, sufferers of trochanteric bursitis may experience hip pain that runs from the hip to the knee area and intensifies when walking, running or sitting in a legs-crossed position. Other symptoms include tenderness around the affected area, swelling, redness and warmth resulting from inflammation or possible infection.
Medical treatment for trochanteric bursitis involves lidocaine or steroid injections into the affected bursa, notes WebMD. Home remedies include rest, ice packs and over-the-counter anti-inflammatory medications. Exercises to strengthen the hip muscles and gentle stretching of the hip and lower back are also helpful.
Sciatic nerve pain presents symptoms of burning, tingling or shooting pain in the hip, buttocks or leg and usually affects one side of the body, WebMD explains. Lumbar spinal stenosis, a narrowing of the spinal canal is one possible cause of sciatic nerve pain, as are degenerative disk disease and pregnancy. Wearing high heels and sleeping on a mattress with limited support may also increase the potential for sciatic nerve irritation.
