What does external malleolus pain mean?

Pain in the external malleolus

The external malleolus is the bony prominence located on the lateral aspect of the ankle, corresponding to the fibula. When this area is painful, swollen, or becomes tender to the touch, the problem may be caused by inflammation, a sprain, or even a more serious injury, such as a fracture.

The main causes

Pain in the external malleolus may be related to:

  • Direct trauma, such as falls or bumps
  • Ankle sprains, frequent in athletes
  • Tendinitis from overload or repetitive movements
  • Osteoarthritis, in older patients
  • Bursitis and local inflammations
  • Neuropathies or irritation of the peripheral nerves

In some cases it may also be a problem with the medial malleolus , with pain extending to the inside of the ankle.
