Ankle joint pain refers to discomfort or soreness in or around the ankle area, often caused by injury, overuse, or underlying medical conditions. Common causes include ankle sprains, fractures, tendonitis, arthritis (such as osteoarthritis or rheumatoid arthritis), gout, or bursitis. Symptoms may include pain when walking or bearing weight, swelling, stiffness, bruising, or reduced mobility. The pain can be sudden (acute) or develop gradually over time (chronic). Diagnosis usually involves a physical examination, imaging tests like X-rays, MRI, or ultrasound, and sometimes blood tests if an inflammatory condition is suspected. Treatment may involve rest, ice, compression, elevation (RICE), physical therapy, medication, or surgery depending on the severity and underlying cause.
