Plantar fasciitis and plantar fibromas are conditions that causes pain in the sole of the foot and heel. The Plantar Fascia is a thick, web-like ligament that connects the heel to the front of the foot. If it is overused or stressed, it can become inflamed and cause severe discomfort and pain.
Heel pain, especially stabbing heel pain, is most often caused by plantar fasciitis, a condition that is sometimes also called heel spur syndrome when a spur is present. Heel pain may also be due to other causes, such as a stress fracture, tendonitis, arthritis, nerve irritation, or, rarely, a cyst.
Because there are several potential causes, it is important to have heel pain properly diagnosed, to distinguish between all the possibilities and determine the underlying source of your heel pain.
The characteristic sign of a plantar fibroma is a noticeable lump in the arch that feels firm to the touch. This mass can remain the same size or get larger over time or additional fibromas may develop. It can develop in one or both feet, is benign (nonmalignant), and usually will not go away or get smaller without treatment.
