Does Your Pump Bump Have One or Two Humps?

It sounds like a catchy lyric from the Black Eye Peas or Beyonce, but “Pump Bump” is a common term used among podiatric physicians. Do you have pain behind your heel? Do shoes irritate areas behind your heel and cause pain? Do you feel an abnormal bump behind your heel? It may be a bump that is irritated by your pump and thus a pump bump!

Pump Bump may also be referred to as a Haglund’s deformity as well as a retrocalcaneal bursitis. Typically, women most commonly complain of the irritation due to their selected shoes designed for fashion rather than comfort. The pain is sharp and along the side of the Achilles tendon insertion into the heel. Many of my patients find significant relief when they wear athletic shoes or backless shoes, but additional treatment is often needed to be completely pain free.

Typically a pump bump is caused by some abnormality in the heel bone. It may be that the heel bone tilts slightly out or pronates. Or, the heel bone may be tilted upward in a high arch. The Achilles tendon is only attached to the middle one-third of the heel bone. The upper one-third of the heel normally allows a nice gliding motion of the tendon like a pulley. When the heel bone is mal-positioned, the gliding motion is less smooth. Eventually, the unusual rubbing of the Achilles tendon causes irritation and the body develops a bursa. The bursa then becomes inflamed and causes pain in the heel.

On examination, the back of the heel will appear red, slightly swollen and painful to the touch. X-rays or ultrasound will often reveal some degree of boney deformity or mechanical disruption.

When changing shoes does not resolve the painful symptoms, it is necessary to see a podiatric physician to begin a treatment regimen that will hopefully keep you out of surgery. A heel lift can be put in the shoe. This will elevate the heel and reduce the area of friction on the shoe. NSAIDs are also used to decrease the inflammation, but it should be noted that if the shoe is still rubbing hard up against the bump the drugs will not be of great effect. Some of my patients have seen great relief by stretching their Achilles tendon 2-3 times a day. In addition, cryosurgery, which is a minimally invasive procedure helps relieve the inflammation along the heel. In most cases, the pain at the back of the heel is due to the constant pulling of the Achilles tendon along a sack of tissue in this area. This is called bursitis. Cryosurgery requires a very small incision along the area and then a probe that sends liquid nitrous oxide at a temperature of (-) 72 degrees is placed into the inflamed area. This reduces the inflammation, thus relieving the pain permanently. One can walk right away after the procedure with their regular sneakers.

Depending on the cause of your bump, orthoses may be necessary to correct the mechanical problem of your heel. Sometimes, the bump is unable to be resolved by the treatments and surgical excision of the bone bump is necessary.
