Common Foot and Ankle Disorders

A common foot complaint is pain in the bottom of the heel. This is often referred to as heel spurs or plantar fasciitis. It commonly is painful the first few steps in the morning or after rest. It tends to get worse the longer one stands during the day. It is caused by subtle changes in foot structure that occurs over time. These changes result in the gradual flattening of the arch. As this occurs a thick ligament (the plantar fascia) that is attached to the bottom of the heel and fans out into the ball of the foot is stretched excessively. This ligament acts as a shock absorber while walking. As the foot flattens it stretches. If it stretches too much it gets inflamed and causes pain. Over time the pull of the ligament creates a spur on the heel bone. It is important to realize that it is not the spur that causes the pain and therefore the spur does not need to be removed in most cases. This condition may also cause generalized arch pain called plantar fasciitis. This is an inflammation of the plantar fascial ligament.

A neuroma is the swelling of nerve that is a result of a compression or trauma. They are often described as nerve tumors. However, they are not in the purest sense a tumor. They are a swelling within the nerve that may result in permanent nerve damage. The most common site for a neuroma is on the ball of the foot. The most common cause of neuroma in ball of the foot is the abnormal movement of the long bones behind the toes called metatarsal bones. A small nerve passes between the spaces of the metatarsals. At the base of the toes, the nerves split forming a "Y" and enter the toes. It is in this area the nerve gets pinched and swells, forming the neuroma. Burning pain, tingling, and numbness in one or two of the toes is a common symptom. Sometimes this pain can become so severe, it can bring tears to a patient's eyes. Removing the shoe and rubbing the ball of the foot helps to ease the pain. As the nerve swells, it can be felt as a popping sensation when walking. Pain is intermittent and is aggravated by anything that results in further pinching of the nerve. When the neuroma is present in the space between the third and fourth toes, it is called a Morton's Neuroma. This is the most common area for a neuroma to form.
