Extensor tendonitis refers to inflammation of the extensor tendons, which run past the front of the ankle and along the top of the foot inserting into the toes. It is an overuse injury that is common in active individuals, especially if your shoes do not fit properly, or are laced too tight.

Symptoms
The main symptom of extensor tendonitis is pain on the top of the foot. It is often described as an aching pain or soreness, which increases with wearing shoes or exercise, in particular, running. Symptoms are likely to develop gradually over time, becoming progressively worse.
You may have some swelling over the top of your foot. And very rarely, some mild redness from shoe irritation. Curling the toes may trigger pain because this places stress on the tendons by stretching them. -
Causes
Extensor tendonitis refers to the inflammation of the extensor tendon and implies a more acute injury. Overuse or repetitive strain is likely the cause. Repetitive strain causes the tendons to become inflamed and eventually degenerate. However, there are a number of factors that may increase your chances of injury. These include:
- Tying shoes too tightly or having a high instep where shoes fit tightly - Running uphill or on a treadmill incline for extended periods - Running on slippery surfaces - Pathological biomechanics
The term extensor tendinopathy is probably a more accurate description of most injuries. This is because it also describes the degeneration of the tendon.
Pain from most long-term, chronic injuries is likely to be degeneration from wear and tear, not tendonitis. Studies have shown that long-term injuries usually do not have inflammatory cells present. -
Treatment
The best treatment is to cease the behaviour that caused the concern, while you let the tendons heal. If you were tying your laces too tightly or incline/uphill running, you’ll want to stop. Training can continue once the inflammation has subsided and you begin to feel better. But easing back into training must be slow. Additionally, ice and anti-inflammatory medications can help when it is acute and newly painful. Once the pain subsides, heat is a better option than ice. Elastic laces may be a great investment as they expand with walking and take the pressure off. Finally, if you are active or walk or stand throughout your day, having a Certified Pedorthist or Registered Chiropodist examine your lower limb mechanics is important. You may be at further risk for injury if a biomechanical condition is contributing to your problem.
