What should you know about a hot swollen ankle?

A recent twist can cause an ankle sprain, while a fall or direct impact may cause a fracture. Joint wear can produce swelling and stiffness through ankle osteoarthritis. Gout is another possible cause: crystals can trigger a sudden, intensely inflamed joint. Infection is less common but urgent, particularly when the ankle is rapidly worsening or you feel unwell. Ankle swelling may also extend beyond the joint after tissue injury.

Stop activities that increase pain and avoid putting full weight on the ankle if walking is difficult. Raise the leg when resting and use a wrapped cold pack for short periods, allowing the skin to return to normal between applications. Keep the ankle protected from further knocks. Do not massage a hot, very tender area or apply heat until a clinician has considered infection and acute inflammation. Arrange a clinical assessment if the swelling is marked, movement is limited, or the cause is unclear.

Seek urgent medical care for fever, chills, spreading redness, a wound near the ankle, severe pain, inability to bear weight, deformity, numbness, or a foot that becomes pale or cold. Prompt assessment is also appropriate when swelling appeared suddenly without a clear injury or continues to increase. These features need examination and may require imaging or tests of joint fluid.

Ask what the examination suggests, whether an X-ray or other test is needed, and which movements or weight-bearing activities are safe. Mention when the warmth began, any injury, skin break, fever, previous gout, and medicines you take.
