What should you know about a swollen ankle with no bruising?

Swelling may appear after twisting the ankle even when skin color stays normal. A small sprain can irritate ligaments and nearby tissues. A fracture can also lack obvious bruising, especially if the injury was less dramatic. Ankle osteoarthritis may cause swelling with stiffness that builds during activity. Sudden heat, redness, tenderness, and severe pain around the joint can occur with gout. Swelling in both legs, or swelling that persists without an injury, needs assessment for causes beyond the ankle.

Rest from running, jumping, and uneven ground. Elevate the ankle when sitting, and use a cold pack wrapped in cloth for short periods if swelling followed an injury. Supportive shoes may feel steadier than loose sandals. Gentle ankle movement within a comfortable range can reduce stiffness, but do not force motion or massage a hot, very painful joint. A clinician may examine the ankle and decide whether imaging is needed; an ankle fracture or ankle sprain can look similar early on.

Seek urgent care if you cannot bear weight, the ankle looks misshapen, pain is severe, the foot becomes cold or numb, or swelling developed suddenly with calf pain or breathlessness. Arrange prompt medical review for fever, spreading redness, a hot joint, worsening swelling, or symptoms that do not begin to settle. If the ankle keeps swelling without a clear injury, evaluation can help distinguish ankle swelling from gout, arthritis, or another problem.

Could this be a ligament injury or a fracture despite no bruising? Do I need an X-ray or another test? Which movements and activities are safe while it settles? What signs would suggest gout or infection?
