Diseases and Conditions

Foot or ankle pain can have many causes. Your type of pain can provide clues to the condition causing the pain. 

You may be experiencing:

  • Acute or severe pain that comes on suddenly usually as the result of an injury or trauma
  • Chronic pain with arthritis or overuse as the most common causes.

How your ankle works

To understand the cause of ankle pain, it's helpful to understand ankle anatomy. The top ankle joint is composed of three bones, the shinbone (tibia), the other bone of the lower leg (fibula) and the anklebone (talus).

  • The knobby bumps on either side of your ankle are the very ends of the lower leg bones. The bump on the outside of the ankle is part of the fibula; the smaller bump on the inside of the ankle is part of the shinbone.
  • The leg bones form a scooped pocket around the top of the anklebone. This lets the foot bend up and down.
  • Right below the ankle joint is another joint, where the anklebone connects to the heel bone. This joint enables the foot to rock from side to side. 
  • Three sets of fibrous tissues connect the bones and provide stability to both joints.

Your Foot
Your foot is made up of 26 bones, 33 joints and hundreds of muscles, ligaments and tendons providing a wealth of opportunities for minor and major injuries.Here are some of the more common foot injuries and conditions:
 
Arthritis
Osteoarthritis and rheumatoid arthritis can cause joint degeneration and pain in both your foot and ankle. The joints most commonly affected by arthritis include:
  • The ankle. The ankle is where the shinbone rests on the uppermost bone of the foot.
  • The three joints of the hind-foot. These joints make up connections between the heel and the mid-foot bones and the uppermost bone of the foot.
  • The mid-foot. This is where one of the forefoot bones connects to the smaller mid foot bones.
  • The big toe. This is also the area where bunions usually develop.
