Symptoms of Bone Necrosis

Avascular necrosis of the femoral head primarily manifests as hip pain or groin pain—often described as a dull, aching discomfort—that typically improves with rest. Pain may also radiate to the proximal thigh or knee. Symptoms often worsen in cold, damp weather. Additional signs include difficulty squatting, inability to sit for prolonged periods, and a waddling gait while walking. It is recommended that patients seek medical evaluation at a hospital to facilitate appropriate diagnostic assessment and rational pharmacotherapy. Furthermore, patients should enhance self-care in daily life to prevent disease progression.
