What It Is
The extensor tendons run along the top of the foot and help to lift (straighten) the toes and the foot. The most common injury to these tendons is extensor tendinopathy (sometimes called tendinitis), where one or more of the tendons becomes painful and swollen because it has been overworked (NHS Lanarkshire, 2023). Typical symptoms are an aching pain on the top of the foot or the front of the ankle that comes on gradually, swelling on the top of the foot, and pain that increases with activity and may be made worse by shoes, especially tight ones (NHS Lanarkshire, 2023).
Less commonly, a tendon on the top of the foot can be torn. This can happen with a deep cut, for example from a sharp object dropped on the foot (Kim et al., 2021), or as a sudden injury during an accident or activity (NHS, 2023).

How to Treat an Extensor Digitorum Tendon Injury
Tips
- Don't lace your shoes too tightly. This can increase the pressure over the top of the foot (NHS Lanarkshire, 2023).
- Long periods of standing, walking or running, especially a sudden increase in these activities, can bring on the condition (NHS Lanarkshire, 2023).
- Poor training technique and not enough recovery between activities can also contribute (NHS Lanarkshire, 2023).
- Shoes that don't fit properly are a common cause of irritation and pressure over the top of the foot (NHS Lanarkshire, 2023).
- Recovery can take time: most people improve within 3 months, though for some it takes up to a year (NHS Lanarkshire, 2023).
- See your family doctor or nurse practitioner if the pain stops you doing normal activities, is getting worse or keeps coming back, has not improved after 2 weeks of treating it at home, or if you have tingling or loss of feeling in your foot, or diabetes and foot pain (NHS, 2025).
Treatment
My Approach
After a Tear or Repair
- If you've had surgery, I need your surgeon's okay before hands-on treatment, and I always work within your team's limits on your boot, splint and weight-bearing
- Work on the calf, the other leg, hips and back, which take extra strain while your foot is protected
- Gentle lymphatic drainage for swelling, and scar work once the wound has fully healed
- Gradual ankle and toe mobility and strength, then a return to walking, running and sport as your team allows

When to get urgent help
Call 911 or go to the emergency room at your nearest hospital if you think you have torn a tendon (sudden, severe pain during an accident or activity, sometimes with a popping or snapping sound) (NHS, 2023), if a cut on the top of your foot may have damaged a tendon (for example, you can no longer lift your big toe properly) (Kim et al., 2021), or if your foot has changed shape or is at an odd angle, or you heard a snap, grinding or popping noise when you were injured (NHS, 2025).
