Not all foot pain is the same, and outside foot pain can have different causes from pain in the heel or arch. If you’re experiencing foot pain on the outside side, it may not be due to an obvious injury or accident, but rather the result of subtle changes in movement, overuse, or foot structure. This type of pain, referred to as lateral foot pain, can make walking, standing, or wearing certain shoes uncomfortable and frustrating. At our orthopaedic clinic in Surrey, many patients from Guildford and surrounding areas come to us seeking answers after struggling with persistent pain that interferes with their daily life. Understanding what might be triggering this pain is the first step toward effective relief.
Peroneal Tendonitis causing outside foot pain
One of the most common causes of outer foot pain is peroneal tendonitis, a condition that affects the tendons running along the outside of the ankle and foot. These tendons help stabilise the foot and ankle during movement, and when they become irritated or inflamed, they can lead to aching or burning discomfort that worsens with activity. This condition often affects runners, people who walk on uneven ground, or individuals who wear unsupportive footwear for long periods. Left untreated, peroneal tendonitis can affect your gait and lead to more widespread discomfort. At our clinic, we frequently manage this condition with a combination of physical therapy, targeted strengthening exercises, and sometimes custom orthotics to reduce strain on the affected tendons.
Cuboid syndrome as a cause of outside foot pain
Another cause worth considering is cuboid syndrome, which occurs when the cuboid bone on the outer midfoot becomes slightly misaligned or restricted in its movement. This often follows an ankle sprain or a sudden twisting injury, although it can also occur gradually in physically active individuals. Patients with cuboid syndrome tend to describe a sharp or localised pain along the outside of the foot that feels worse when pushing off during walking or when bearing weight for extended periods. Manual mobilisation of the cuboid joint, combined with supportive taping and specific exercises, can be highly effective. A careful physical examination is often enough to diagnose the issue, though imaging may sometimes be used to rule out other conditions.
Outside foot pain as a result of stress fractures
For individuals who have recently increased their activity levels, especially in sports or exercise routines involving running and jumping, stress fractures in the fifth metatarsal are another possible explanation. This bone runs along the outer edge of the foot and can develop small cracks from repetitive pressure. Stress fractures are typically not linked to a single traumatic event, but rather to a build-up of force over time. The pain often starts as a dull ache and gradually becomes more intense with weight-bearing activity. Unlike acute fractures, these injuries may not show obvious swelling or bruising, which is why patients often delay seeking help. Early diagnosis using imaging and a period of rest or protective footwear is crucial to ensure proper healing and to prevent complications.
High foot arches
In some cases, the cause of foot pain on the outside side may relate to structural factors, such as high foot arches. Individuals with high arches often place more pressure on the lateral edge of the foot when walking or running, which over time can lead to chronic strain and irritation of the surrounding tissues. This imbalance can also contribute to foot arch pain, especially after long periods of standing or walking. Many patients are unaware that their foot shape is contributing to their symptoms until they receive a proper assessment. Addressing biomechanical issues with non-surgical options like tailored physiotherapy or supportive insoles can significantly improve comfort and reduce strain on the outer foot, particularly when combined with footwear advice and strengthening exercises.
Ankle instability causing outside foot pain
Another frequently overlooked cause of outer foot pain is ankle instability following a previous sprain. Even if the original injury seemed minor or healed quickly, the ligaments around the ankle may not have fully regained their strength or range of motion. This lingering instability can place extra pressure on the lateral structures of the foot, resulting in pain that feels like it has developed without a clear reason. This issue can become particularly noticeable when walking on uneven surfaces or during sudden changes in direction. A structured rehabilitation programme focusing on joint stability, balance, and coordination can make a lasting difference and prevent further flare-ups. We regularly provide this type of support as part of our foot pain diagnosis and treatment in Surrey, helping patients return to normal activity with greater confidence.
Although some cases of lateral foot pain improve with rest, not all causes will resolve on their own. If your symptoms have persisted for more than a few days, are worsening with time, or are affecting your ability to stay active, it is important to seek a professional opinion. Delaying care can lead to further complications or longer recovery times. Our clinic offers expert assessments for patients dealing with foot pain on the outside, whether due to biomechanical problems, tendon strain, joint restriction, or overuse injuries.
