Foot Tendonitis Treatment. Foot tendonitis can sometimes happen in athletes, runners and people who are on their feet a lot. Foot tendonitis is a classic overuse injury and impacts a specific tendon within the foot, the posterior tibial tendon. Posterior tibial foot tendonitis is a common problem of one of the tendons on the inner side of the ankle.
