Gluteal tendinopathy
Women over 40, especially around menopause, and runners who recently added mileage or hillsThe gluteus medius and minimus tendons attach to the greater trochanter, the bony point on the side of the hip. Compression and overload can cause these tendons to thicken and become painful, a condition called gluteal tendinopathy. It is the most common driver of what used to be labeled trochanteric bursitis.
The clue: Pain lying on the sore side, and pain within 30 seconds of standing on that leg alone, are the classic clues.
Trochanteric bursitis
Adults with gluteal tendinopathy, a leg length difference or a recent fall on the side of the hipA bursa is a small fluid sac that reduces friction between tendon and bone. The trochanteric bursa can become inflamed alongside an irritated tendon or after a direct blow. Bursitis on its own is less common than once thought, and the tendon is usually involved too.
The clue: Tenderness right over the bony point after a fall or a long walk, with swelling seen on ultrasound, suggests bursitis.
Gluteus medius or minimus tear
Adults 50 and older with long-standing outer hip pain, more often womenOver time a worn gluteal tendon can partly or fully pull away from the bone. This weakens the muscles that keep the pelvis level when you walk. Tears are sometimes called a rotator cuff tear of the hip.
The clue: A new limp, or the pelvis dropping on the opposite side when you stand on the painful leg, points to a tear.
IT band irritation and external snapping hip
Runners, cyclists and dancersThe iliotibial band is a thick band of tissue running down the outside of the thigh. It can rub or snap over the greater trochanter, irritating the tendon and bursa underneath. Many people feel a visible snap when they walk or swing the leg.
The clue: A snap you can see or feel on the outside of the hip, with soreness in the same spot, suggests the IT band.
Referred pain from the lower back
Adults with arthritis or disc problems in the lumbar spinePinched nerves in the lower back, especially at the L4 and L5 levels, can send pain to the outer hip and down the side of the leg. The hip itself may examine normally. Dr. Stride checks the back at every visit for this reason.
The clue: Outer hip pain that travels below the knee with numbness or tingling usually starts in the spine.
Meralgia paresthetica
People who wear tight belts or work belts, pregnant women, and adults with diabetes or recent weight gainA sensory nerve called the lateral femoral cutaneous nerve can be squeezed where it passes near the front of the pelvis. It causes burning or numbness over the outer thigh. It does not cause weakness.
The clue: A burning, numb patch on the outer thigh with no tenderness at the bony point of the hip is the giveaway.
