Pain On Outside Of Foot

1)  Stress Fractures

Stress fractures are a common cause of pain on outside of the foot.  They occur when there is a small break in one of the foot bones usually from repetitive sporting activities.

2)  Ankle Sprain

Ankle sprains are the most common cause of pain on the outside of the foot following an injury accounting for 85% of ankle injuries. The ligament is damaged when we roll the foot inwards as the ankle rolls outwards, known as an inversion injury.  This leads to some or all of the ligament fibres being torn causing side of foot pain, swelling, bruising and instability. 

3)  Cuboid Syndrome

Cuboid Syndrome is a less common cause of lateral foot pain (i.e. outer side of foot pain) but it frequently goes undiagnosed which can lead to symptoms being present for long periods. Anyone with ongoing lateral foot pain for more than 3 months following an ankle sprain should be assessed for cuboid syndrome.

4)  Peroneal Tendonitis

Peroneal Tendonitis is another common cause of pain on outside of foot and around the heel.  It develops when there is repetitive tension through the peroneal tendons of the foot causing irritation, inflammation and degeneration. 

It is usually caused by frequent overuse such as long distance running, abnormal foot position, muscle imbalance or after an ankle sprain. 

5)  Arthritis

Arthritis can cause pain anywhere in the foot but often results in side of foot pain.  There are two common types of arthritis – rheumatoid arthritis aka inflammatory arthritis and osteoarthritis aka degenerative arthritis.  Foot pain from rheumatoid arthritis is the more common of the two. Symptoms often come and go, varying in severity.”
