People with tendonitis in the foot experience pain when attempting to move the affected foot, as the American Podiatric Medical Association explains. Tendons in the foot may also swell when tendonitis is present.
Tendonitis occurs when the tendon in the foot is inflamed, according to the American Podiatric Medical Association. The condition can occur as a result of improper stretching, overuse, physical exertion or injury. Individuals with arthritis, tight tendons and flat feet may be more prone to tendonitis.
Home treatments for tendonitis in the foot include rest and ice to relieve the pain, as recommended by the American Podiatric Medical Association. Patients should restrict activity, avoid bearing weight on the foot and apply ice three to four times each day for at least 15 minutes each session. Pain that continues for longer than one week should cause concern, and patients should consult with a podiatrist to determine if the tendonitis is a symptom of a more acute injury or chronic problem.
Medical professionals diagnose tendonitis by completing a routine physical exam and inquiring about the patient's general health. Doctors may also use X-rays or an MRI of the foot to diagnose the condition, according to the American Podiatric Medical Association. Its treatment typically focuses on preventing further injury and relieving pain in the foot.
