Irregular nodule of collagen fibers within the connective tissue of the plantar fascia
As stress is placed on the plantar fascia, the tissue can undergo small tears. The body rapidly lays down collagen fibers to repair damage, typically in an irregular and erratic way causing tissue to bulge. The plantar fascia can be stressed within conventionally shaped footwear that elevates the heel and the toes, keeping the plantar fascia in a chronically stressed and lengthened position. With repeated stress, the plantar fascia continues this tear/repair process, increasing the size of the nodule slowly over time.
