If you experience sharp pain on the outside of your foot while running, this could be due to tendonitis. This could be caused by overexerting yourself during training sessions or switching up your routine; or by wearing trainers that are too soft.

Symptoms may include pain on the outer side of your foot, an apparent lump in that area and/or swelling. Problems in this region could include Jones fractures, stress fractures or peroneal tendonitis.

Peroneal Tendonitis

Peroneal tendonitis occurs when the peroneal tendons that run from your lower leg through to the outside of your foot and ankle become inflamed, typically as a result of overuse or increased loads that cause them to rub against bone causing friction. Symptoms may include pain on the outside of your foot and ankle, swelling, snapping sensation when turning your ankle, and weakness in both feet and ankles.

Medical professionals typically diagnose running injuries by reviewing your running history and performing a physical exam, which includes moving the feet and ankles in various positions to detect tenderness or any tender spots in them. If they suspect anything may be amiss, an MRI or ultrasound examination may also be required.

Plantar Fasciitis

Plantar fasciitis is a condition characterized by heel pain caused by irritation of the dense tissue bands that connect your heel to your toes, such as running or other activities that put additional stress on your feet. It can be made worse through running, or any activity where feet experience added pressure such as hiking.

Health care professionals can diagnose this condition based on your medical history and physical examination, checking your feet for tenderness and the source of pain. They may also order an X-ray or MRI to rule out other issues causing discomfort.

Stretches that help maintain flexible foot, ankle, and calf muscles will aid this condition. Ice therapy may also prove beneficial; using cloth-covered ice packs multiple times per day or rolling frozen water bottles under your heel for an ice massage massage can significantly decrease pain and swelling.

Stress Fractures

Stress fractures are injuries sustained through running or other weight-bearing exercise that expose bones to repetitive stress, causing them to break down faster than they can heal. Symptoms may include pain with activity, swelling and sometimes an imprint-shaped depression in the bone that becomes visible with an X-ray; however, due to starting in bone marrow.

As soon as you experience symptoms of a stress fracture, it is crucial to stop exercising immediately and wait for medical clearance before returning to activities. A stress fracture typically takes 6-8 weeks to heal completely, and returning too early could prolong this process or even worsen its effects.

Cuboid Syndrome

Athleticians and those putting intense strain on their feet such as dancers and runners are at increased risk for cuboid syndrome. This injury occurs when joints and ligaments surrounding the cuboid bone become damaged or dislodged from its normal location, causing sharp pain on the outside of your foot that comes and goes over time.

Medical professionals typically utilize patient history review and gait observation in order to accurately diagnose this condition. A physician may notice that a patient’s symptoms match up with stress fracture or ankle sprain.

For an accurate diagnosis of cuboid syndrome, doctors will typically employ manipulation techniques to return the dislocated cuboid bone back into its original position and reduce or cease symptoms (Blakeslee and Morris 1987; Jennings and Davies 2005). Furthermore, low dye arch taping or padding may also be utilized alongside cuboid manipulation for effective relief.

Bunions

Bunions are common among runners, caused by repeated stress on the big toe joint that leads to its bone shifting out of position and creating an unsightly bump inside your foot. They may become even more noticeable when running as your feet come into direct contact with the ground more frequently than they would when walking or standing still.

To reduce bunion pain, try wearing shoes with wide toe boxes that reduce rubbing. Protective pads designed specifically to protect bunions can also help. Icing will also help decrease swelling. In more serious cases, surgery may be required; in these instances physical therapy sessions may provide valuable exercises and stretches designed to keep feet healthy.
