Have you ever felt a sharp pain in your heel while walking or running? It can feel like a needle pricking you, or someone squeezing you hard, or even a bruise. This annoying pain can make it very difficult to do your daily activities. One of the main reasons for this is a problem that occurs in the fat pad of the heel, which we are going to talk about today, a condition called `(Heel Fat Pad Syndrome)`.
What is `Heel Fat Pad Syndrome`?
Simply put, the thinning of the fat pad in your heel, or the loss of its elasticity, is what we call ``Heel Fat Pad Syndrome''. Imagine, under our heels, on top of the bone, there is a thick layer of fatty tissue, like a natural mattress . This is what protects our heel bone (`heel bone` or `calcaneus`) from the shock of the ground when we walk, run, and jump. It works like a ``shock absorber`` in a car. Over time, due to various reasons, this fat pad wears down and its cushioning properties decrease, which is when pain begins to occur.
You may have heard this condition called `fat pad atrophy`, `fat pad syndrome`, or `heel fat pad atrophy`.
How common is this condition?
In fact, Heel Fat Pad Syndrome is the second most common cause of heel pain, after Plantar Fasciitis. However, it is often confused with Plantar Fasciitis, as the symptoms can be quite similar. Therefore, it is important to identify the exact cause.
What are the symptoms of ``Heel Fat Pad Syndrome''?
See if you have any of these symptoms:
- A sharp, deep, bruise-like pain that comes from the middle of the heel when walking, standing, or running.
- When you press hard on the middle of your heel with your finger, the same pain I mentioned earlier reappears.
- The pain is clearly increased when standing for long periods of time, when doing high- impact exercises (for example, jumping, sprinting, gymnastics, basketball), or when walking on hard surfaces (such as wood, concrete, ceramic tiles) without shoes .
If the condition is not severe, you may not experience any major symptoms. Or you may only feel a little pain occasionally when walking barefoot, running, or pressing your toes against your heel.
What are the main reasons for this?
This condition called ``Heel Fat Pad Syndrome'' does not develop overnight. The main cause of this is ``wear and tear'' that occurs over time. There are several factors that contribute to it:
- Ageing: Many things in our body change with age. Similarly, the fat layer on the heels gradually thins, the amount of fat in it decreases, and its elasticity may decrease.
- Weight gain: As we gain weight, the pressure on the fatty layer in our heels increases. This causes it to wear out quickly, losing its flexibility and cushioning properties.
- Family history: If someone in your family has had this condition, or if you have a disease that affects the connective tissue of the body (such as lupus or rheumatoid arthritis), you are at higher risk of developing this condition.
- Trauma to the heel: If you receive a hard blow to the heel, like suddenly jumping from a height, that can also be a cause.
- Gait imbalance: If there is any imbalance in the way we walk (gait) – that is, the way our feet strike the ground, the way our body weight is distributed across the feet – over time, the fat layer on the heels can wear down unnaturally.
- Foot structure: Some people have changes in the position of the arch of their foot (e.g. flat feet or high arches) and gait problems, which can put extra pressure on the heel.
- Improper footwear: A big reason for this is the continuous use of shoes or sandals that do not provide support or shock absorption for the foot . Then all the pressure comes to the heel, and the fat layer wears away quickly.
- Walking on hard surfaces: Frequent walking or running on hard surfaces like concrete or tiles without sandals has a major impact on the fatty layer of the heel.
- Certain activities that you do frequently: Activities that frequently cause your heels to hit the ground (e.g. running, basketball, tennis, volleyball, gymnastics) and standing for long periods of time can cause this condition.
- Previous Corticosteroid Injections: Sometimes, steroid injections called corticosteroids, which are used to treat other foot pain and swelling, can cause the heel fat layer to thin and shrink as a side effect. Frequent steroid injections to the heel can increase this risk.
This can also be caused by certain medical conditions.
- Plantar Fasciitis: This is an inflammation of the thick ligament called the plantar fascia that runs from your heel to your toes. This also causes heel pain.
- Heel Spurs: When small, thorn-like protrusions (`heel spurs`) form on the heel bone, they can put pressure on the ligaments of the foot and reduce the flexibility of the heel's fatty layer.
- High arch feet: Some people have an abnormally high arch in their feet. This can permanently change the structure of the foot and affect the ligaments in the foot.
- (Type 2 Diabetes): People with Type 2 Diabetes may experience a breakdown of the fat and an important protein called collagen in the fat layer.
- Lupus and Rheumatoid Arthritis: These autoimmune diseases affect the body's connective tissue, including the connective tissue in the feet.
How do doctors recognize this condition?
When you go to see a doctor with heel pain, he or she will first ask you about your medical history and current symptoms.
You may hear things like this, especially about your heel pain:
- How does the pain feel? (e.g., is it tight, stabbing, or throbbing?)
- What time of day do you feel the pain?
- What kinds of things make the pain worse?
- How long has this pain been there?
- Does the pain decrease with rest?
Next, the doctor will do a physical exam of your foot. They will look for any structural problems in the foot and whether you feel pain when you press on the middle of the heel. They may also compare the thickness of the heel fat pad when you are standing and when you are not standing. A healthy heel fat pad should be between 1 and 2 centimeters (0.4 and 0.8 inches) thick. If the heel fat pad feels hard or firm to the touch, it means that it is less flexible. This can also be a sign of this syndrome.
Sometimes, to confirm the exact condition and to rule out other causes of heel pain (e.g., a fracture, a heel spur), an X-ray, an ultrasound scan, or possibly an MRI (Magnetic Resonance Imaging) may be recommended.
What are the treatments for this?
The good news is that this condition can often be managed with simple, at-home treatments (`conservative treatments`). The main goals of these treatments are:
- Reducing pain and swelling.
- To protect the existing fat layer.
- Preventing further damage to the fat layer.
In some severe cases, more complex treatments (`advanced techniques`) may be necessary. These involve adding additional materials to increase the thickness of the fat layer in the heel.
Simple (conservative) treatment methods:
- Rest: Rest your legs as much as possible. Limit high-impact activities (such as vigorous jumping and running) that can cause heel pain.
- Apply ice: After an activity that causes pain, apply an ice pack to your heel for about 20 minutes. You can do this several times a day.
- Medication: Over-the-counter medications can be used to reduce pain and swelling. Examples include ibuprofen (Advil®, Motrin®) and naproxen (Aleve®). However, it is always best to consult a doctor before taking any medication.
- Orthopedic footwear: Wear orthopedic shoes that provide good support and cushioning, especially for the heel. You can get advice from a podiatrist or a specialty store that sells such shoes.
- Taping your heel: This is a method of placing the heel bone under the heel bone and applying special tape to the heel to provide support and cushioning. Your doctor or physical therapist will show you exactly how to do this.
- Heel cups, shoe inserts and cushioned socks: Heel cups, shoe inserts and cushioned socks, available at pharmacies or online, provide extra cushioning and support for your heels.
- Exercise program: Under the guidance of your doctor or physical therapist, you can learn stretches that stretch your calf muscles and rehabilitation exercises that can help you maintain proper foot-knee-hip alignment and correct imbalances.
Advanced (complex) treatment methods:
- Injectables: In this method, various natural or synthetic or liquid filler materials are injected into the fat layer of the heel to increase its thickness. For example, there are dermal fillers that contain things like Poly-L-lactic acid and Hyaluronic acid. Silicone is also sometimes used, but there is controversy about its use because it can travel to other parts of the body and can cause mild to severe reactions. The effects of these dermal fillers usually last about 6 to 12 months. It depends on things like your lifestyle, activity level, body weight, and age.
- Fat grafting (or autologous fat transplantation): This involves taking a small amount of fat from another part of your body (such as your thigh or abdomen), cleaning it, and transplanting it into the fat pad in your heel (transplantation). This is usually an outpatient procedure. The results are longer-lasting than dermal fillers.
- Allografting: This method uses fat tissue taken from another person (a donor). Since only fat cells are used, there is very little chance of rejection by the body. This is also a surgical procedure. It takes a little longer to heal than other methods (it can take about 6-8 weeks for the new tissue to fuse with the existing tissue). It is reported that this treatment can provide pain relief for about 5 years.
Sometimes, if congenital or acquired physical deformities in your toes, feet, ankles, legs, knees, or hips change the way your body distributes weight when you walk, and if this significantly affects your life, making it impossible to perform daily activities, doctors may consider surgery to correct the deformity.
What happens if left untreated?
If you ignore the condition ``Heel Fat Pad Syndrome'' without treatment, the following problems can occur:
- The pain will continue. It can reduce your quality of life.
- It becomes difficult to walk, play sports, and perform daily tasks.
- You may unknowingly change the way you walk to reduce pain, which can put unnecessary pressure on other joints in the body, increasing the risk of falls and other injuries.
How can this situation be prevented?
Although we cannot completely stop the things that happen with age or genetic predispositions that run in families, we can reduce the risk of developing this condition (Heel Fat Pad Syndrome) by changing some lifestyle habits and taking preventive measures:
- Always wear shoes that fit your feet well, have good heel support, and cushioning. Wear appropriate athletic shoes when doing high-impact activities.
- Avoid wearing high-heeled shoes frequently. They don't distribute your body weight evenly across your feet, instead putting more pressure on one specific area of your foot (often the front).
- Limit activities that put a lot of pressure on the heels, such as running, basketball, and gymnastics. Give the heel fat pad time to recover after such activities.
- Maintain a healthy body weight. Being overweight increases the pressure on your heels.
- Avoid walking barefoot as much as possible, especially on uneven, hard surfaces (like tile, wood, cement).
- Check all your shoes regularly. If the sole of your shoe is worn out in one way or another (like one side is more worn out), or if the cushioning inside the shoe no longer feels supportive, replace the shoe.
Can this `(Heel Fat Pad Syndrome)` be completely cured?
To be honest, there is no such thing as an "absolute long-term cure" for ``Heel Fat Pad Syndrome''. Because, as we age, and as we walk, run, and jump normally (``natural wear and tear``), the fat pad in the heel shrinks and thins to some extent. However, as mentioned earlier, if you take the necessary steps to reduce heel pain, swelling, and prevent further damage to the fat pad, you can definitely improve your quality of life and continue to engage in the activities you enjoy.
What is the difference between `(Heel Fat Pad Syndrome)` and `(Plantar Fasciitis)`?
This is a point where many people get confused, so it's important to know some of the key differences between these two conditions.
Think about it, ``Plantar Fasciitis`` is a weakening, swelling, or inflammation of the ``plantar fascia``, a thick band of connective tissue that runs along the bottom of your foot, from your heel to your toes. This ``plantar fascia`` is what provides support for the ``arch`` of your foot.
- The main symptom of plantar fasciitis is a throbbing pain in the heel. This pain is usually located on the inside of the heel, near the sole of the foot. Sometimes the pain can also spread along the arch of the foot.
- When you stretch your leg, you feel a tightness and a pulling sensation in the sole of your foot.
- The most important thing is that the pain is most severe when you first get out of bed in the morning and take the first few steps. Even though the pain seems to subside after walking a little, if you continue to put weight on the leg, the pain increases again at the end of the day.
- During a medical examination, if the `plantar fascia` is pressed, a sharp and stabbing pain occurs, as if it were being stabbed with a needle.
However, in `(Heel Fat Pad Syndrome)`:
- The pain is in the middle of the heel, like a deep, close-up bruise.
- The pain is most common when walking, standing, or doing high-impact activities for long periods of time. The pain is even worse when walking on hard surfaces without sandals.
- This pain can occur at any time of the day, at night, or even when resting.
- Heel Fat Pad Syndrome is more likely to occur in both feet at the same time than Plantar Fasciitis.
Important: Sometimes both of these conditions can occur together. Also, a person with `(Plantar Fasciitis)` can later develop `(Heel Fat Pad Syndrome)`. Do you know how that happens? When the ``Plantar fascia`` is damaged, the weight of the foot is not distributed properly when walking or running. Then, more pressure is put on the fat pad of the heel, which tries to relieve it quickly.
Let's learn a little about a calcaneal stress fracture.
One more thing you should know. The bone in your heel is called the calcaneus. Repetitive movements like running can cause a small crack or break in the calcaneus. This is called a stress fracture. If you have a calcaneal stress fracture, you will feel pain in the heel and the back of the heel. This heel pain will gradually increase over time. At first, it will only be there during activity, but later it will start to hurt even when your leg is at rest. You may need to have a bone scan, CT scan, or MRI scan to determine if your heel pain is due to a stress fracture.
Finally, what to remember (Take-Home Message)
So, simply put, heel fat pad syndrome is the loss of the thick, cushion-like layer of fat in the heel area of our feet that helps support our body weight and protects us from shocks. This can be caused by many factors, including age, activities that put pressure on the heel, weight gain, and uneven weight distribution while walking. The main symptom is a sharp, deep pain in the middle of the heel.
The best part is that simple treatments like rest, painkillers, ice, proper footwear, and exercise as directed by your doctor can often help manage this condition. In some severe cases, more advanced treatments are available.
If you have persistent heel pain, don't ignore it. Definitely see a doctor for advice. The sooner you identify what the problem is, the sooner you can start the right treatment. Then you can prevent the condition from getting worse, get well soon, and go about your daily activities with joy!
