• A pump bump, also called **Haglund’s deformity**, is an enlargement of the back of the heel bone that becomes irritated by rigid dress shoes. The friction leads to inflammation of the overlying bursa, causing sharp posterior heel pain.
• Symptoms include a painful, swollen, or reddened bump on the back of the heel, worse in dress shoes and often less noticeable in sneakers or when barefoot. The top edge of the shoe typically rubs directly over the irritated area.
• The condition develops when repeated pressure from stiff shoes irritates the heel bone, causing it to enlarge. A protective bursal sac forms over the bone and can become inflamed, resulting in bursitis and increased pain.
• Treatment focuses on reducing shoe irritation. Helpful measures include switching to softer or lower‑cut shoes, adding a small heel lift, using gel pads, short‑term anti‑inflammatory medication, and targeted physical therapy. Cortisone injections may help when placed carefully to avoid the Achilles tendon.
• Surgery is considered when conservative care fails. The procedure removes the excess bone and inflamed bursa, typically reserved for patients who have already stopped wearing the aggravating shoes but still experience persistent pain.
The most common cause of pain in the back of the heel that I see is generally referred to as pump bump also known as Haglund's deformity.
Not coincidentally, you will notice that the top of the patient’s dress shoe just happens to cut across the heel at that level.
What has happened is that through constant wearing of dress shoes, the shoe itself has irritated the underlying bone, the bone has slightly enlarged as a result of that irritation and in an effort to protect the area of irritation, the body has formed a bursal sac which itself has become inflamed and is now a bursitis.
Below is the usual site for a ‘pump bump’ or bone spur with bursitis.

The obvious treatment for this type of posterior heel pain would be to avoid wearing the shoes that aggravate the problem; that is easier said than done. I have been in this business long enough to know that a fashionable woman is going to continue to wear the shoes that look the best even though they might not feel the best.
That said, sometimes adding a small heel lift to the shoe will help as it may raise the heel just enough so that the top back portion of the shoe does irritate the enlarged bone and bursal sac.
If the area is not too inflamed and painful, one may try some of the new gel cushions that are available in an effort to reduce friction.
From a medical stand point, short term anti-inflammatory medication may help but of course will not cure if the shoe is still irritating the area.
Cortisone injection many times is very helpful, the key is to inject just under the skin and avoid the Achilles tendon which can weaken from this type of injection.
Physical therapy is also very helpful in alleviating this type of pain.
Surgical intervention should be considered in instances where conservative measures fail. In this case, the overgrowth of bone is removed as well as the overlying bursitis. This is usually reserved for people who have stopped wearing the shoes that originally caused the problem, but are still having posterior heel pain nonetheless. Unfortunately, many foot problems can continue to be bothersome even when the causative agent is identified and removed. (Once you have it; you have it!)
The other type of posterior heel pain that we see involves irritation of the Achilles tendon. The cause of this irritation may be due to trauma directly to the tendon, overuse of the tendon which is particularly a problem in men over the age of 40 who continue to play a lot of sports. People who have a tight heel cord, whereby it is very difficult to raise the foot at the level of the ankle, are more prone to Achilles tendon problems.
Below is a picture of the Achilles tendon.

The patient will present with tenderness and possibly swelling in the area of Achilles tendon anywhere from where it attaches into the heel bone to just above the ankle. An x-ray may also reveal the formation of bone spurs at the level where the tendon attaches into the heel. The spurs can become painful if they are irritated enough.
Further complicating the situation is the fact that there is a natural occurring bursal sac that sits between the heel bone and Achilles tendon which may also become inflamed and painful in the process.
If there has been trauma to the area it is important make sure all or part of the tendon has not torn. You should see a doctor right away, even though you may be able to walk, you may still have a partial tear. A torn Achilles tendon is a very debilitating condition.
Icing the area for 24 hours can be very helpful as well as anti-inflammatory medication. Rest would also be advised. I am not big on ice after 24 hours; I generally switch my patients to heat in an effort to increase blood flow to the area to enhance the healing.
If the Achilles tendon has been strained rather than traumatized, the above applications apply. Adding a one quarter inch heel lift can be of benefit because it will shorten the tension on the heel cord especially in those who exhibit a tight Achilles tendon. If the strain is severe enough immobilization of the ankle may be necessary.
see related article....Achilles tendonitis
This condition is more of a board question than a medical problem seen with any frequency. The plantaris tendon travels down the back of the leg and runs parallel and medial to the Achilles tendon. Its insertion is into the posterior aspect of calcaneus in the same area that the Achilles tendon attaches.
I mention it because on rare occasions there can be an inflammation of the plantaris tendon and it is mistaken for Achilles tendonitis.
This tendon happens to be so thin that it goes by the name of Freshman's nerve because in anatomy class it is mistaken for a nerve.

I've been doing some aggressive research lately (it's how I found your incredible website) and realize now that my symptoms are not consistant with the diagnosis.

Dear Dr.Mitnick
I usually do my research on the Mayo clinic website. I think your website is the most informative site I have found when researching foot pain.
I thank you for putting together this incredible website.

First, I want to let you know that you have the best web site I've found related to foot issues. (The only thing I had difficulty finding was the "ask a question" page.)

I received the orthotics Monday afternoon and began wearing them Tuesday. After two days I would say that I have noticed a huge improvement in the discomfort I have been experiencing. My foot feels better than it has in months.

I used to work for a podiatrist (front desk) back during summers in college years ago, so I know the benefits of good care. Again, I want to thank you for an EXCELLENT website. It was so great to get to your site (top of google search) and actually find all the answers I needed EASILY and QUICKLY! Clearly you put a ton of work into it and I really appreciate it.
All the best,

By the way, millions of websites could use yours as a guideline on how to organize information and make the site user-friendly. Kudos to you!
