One of the most common complaints for foot pain is the result of tendonitis which occurs when a patient compensates from another foot problem. There are two tendons known as the peroneous longus and peroneous brevis which prevent the foot from inverting or turning in when walking. Essentially they are stabilizers and prevent you from spraining your ankle. If anything occurs to your foot that causes you to "limp", these tendons work harder as you compensate.
