What's Causing My Side Foot Pain?

So as you can see there are lots of possible causes of lateral foot pain: 

At The Doctors

Any new incidence of pain on the outside of the foot that doesn't settle down within a few days should be assessed by your doctor. At your appointment they may:

Take A History: Asking lots of questions to find out e.g. when & how the foot pain started, how it's behaved since, any other symptoms, anything that makes it better or worse and pain severity

Examine Your Foot: Looking at the appearance, movement, strength, functional activities involving the foot e.g. walking, special tests e.g. to look at integrity of the ligaments

Order Further Investigations: If they feel there may be bone damage you will be sent for an xray. Soft tissue injuries may require ultrasound, CT or MRI imaging. You may also be sent for a blood test

Treatment: Once the doctor has identified what is causing your pain on the outside of your foot, they will advise you on appropriate treatment e.g. exercises, physiotherapy, orthotics or rest.

If you have injured your foot, have severe foot pain, are unable to walk, have lost sensation in your foot, or your foot has changed colour, see your doctor immediately.

Treating Pain On Outside Of Foot

The best treatment for pain on the outside of the foot will depend on what is causing it and what stage you are at in the healing process.

  • Rest Ice Compression Elevation: Generally, the best place to start is with RICE - a combination of resting from aggravating activities, regularly applying ice, wearing a compression bandage to reduce swelling and support the foot and elevating the leg to help reduce swelling.

  • Exercises: After a few days, any swelling should have started to go down and in most cases you can start some gentle foot and ankle exercises. This helps you to regain the full range of movement and strength, aids healing by bringing fresh nutrients to the injured area and puts the right stresses and strains through the soft tissues so that they heal fully in the correct position.
