Have you ever noticed a small swelling on the outside of your ankle, a little lower down, with pain? Perhaps this pain is worse when you walk or turn your foot here and there. If this has happened to you, then we are going to talk about something that may be important to you. We call this condition ``Sinus Tarsi Syndrome``. Don't worry, let's talk about it simply.
What is Sinus Tarsi Syndrome?
Simply put, Sinus Tarsi Syndrome is a painful swelling on the outside of your ankle, just below it. To be precise, it is caused by inflammation of the subtalar joint, where your ankle bone (Talus) and heel bone (Calcaneus) meet.
This `(Subtalar joint)` is what helps you turn your foot from side to side. The `(Sinus Tarsi)` is the small space between the two bones I mentioned. Think of it like a small tunnel through a mountain. But instead of removing rocks to make a road for cars, this is a small road carved out of the bones. Through this road run `(ligaments)` (bones), nerves and blood vessels that go to the other parts of your foot and ankle.
Sinus Tarsi Syndrome occurs when the tissues in the sinus tarsi become irritated for some reason. The tissue swells. When this swelling occurs in this small space, the pressure inside increases and pain occurs. Ankle sprains are the main cause of this. This risk is especially high if you have sprained the same ankle several times.
If you have pain or swelling in your ankle or heel, and if you have difficulty moving or using your foot and ankle properly, you should definitely see a doctor or a podiatrist.
Is this a common condition?
According to experts, Sinus Tarsi Syndrome is a relatively rare condition. However, it is difficult to say exactly how common it is. This is because many people with this condition may not be properly diagnosed. Also, its symptoms are very similar to those of other ankle disorders.
What are the symptoms of Sinus Tarsi Syndrome?
The main symptoms of this condition are pain and swelling in the ankle. The pain and swelling are most often felt on the outside of the ankle, on the lower edge. However, sometimes this pain can spread to other parts of the ankle as well.
You will likely see and feel swelling in the area between the ankle bone and the heel bone. Sometimes this swelling is so obvious that some people think it looks like a cyst under the skin.
What kind of feeling does this give you?
The pain of Sinus Tarsi Syndrome is usually constant and mild.It feels like a constant ache. But when you move or use your leg, the pain becomes sharp and can feel like a knife stabbing you. Especially during these times:
- When your foot is turned out in the middle of your body.
- When you put weight on your feet, such as when walking, running, or climbing stairs.
- When you touch and press on that part called the sinus tarsi.
Why does Sinus Tarsi Syndrome occur?
Any injury or condition that damages your subtalar joint or the space called the sinus tarsi can cause this.
Ankle sprains are the most common cause. About 80% of people with sinus tarsi syndrome have this condition when their ankle is twisted outward from the center of the body. Slips, falls, and other sports-related injuries are the most common causes of ankle sprains. For example, if you suddenly trip while playing cricket, or if you accidentally trip and roll your ankle while walking in a pothole. These are the most common causes of this condition.
Ankle injuries can also cause a condition called synovitis (swelling of the synovial membrane) in your subtalar joint. The swelling that results can also lead to sinus tarsi syndrome.
Non-injury causes
Sometimes, the natural position of your feet, the way you walk, and certain health conditions can cause your sinuses to put undue pressure (`stress`) over time, leading to this syndrome. Causes that don't involve injury include:
- Having flat feet.
- Overpronation (over-pronation) is when the foot rolls inward too much while walking or running.
- Arthritis conditions of the feet and ankles.
- Obesity.
Who is at higher risk?
Ankle sprains are such common injuries that anyone can develop sinus tarsi syndrome. However, the following people are at a slightly higher risk:
- People who play sports that require sudden changes of direction and twists (e.g., football, basketball, hockey).
- People who stand for long periods of time and work on hard ground.
- Pregnant women. Overpronation (the inward rolling of the foot) is more likely to occur during pregnancy.
- People who have sprained the same ankle multiple times. If a previously injured ankle is sprained again, the risk of developing sinus tarsi syndrome is much higher.
How do doctors diagnose this accurately?
A doctor will diagnose sinus tarsi syndrome by doing a physical exam . He or she will look at your injured ankle, check for swelling, and palpate the area called the sinus tarsi. You may be asked to stand, walk, or shake your ankle. If the pain gets worse or worsens when you touch, move, or move your ankle, you should tell your doctor.
If you know when you first felt the symptoms, especially when and where the injury occurred, tell your doctor about those details.
The symptoms of sinus tarsi syndrome are similar to those of several other conditions that affect the ankle and foot. For example:
- Foot and ankle arthritis.
- Calcaneal stress fractures.
- Talus fractures.
- Tarsal tunnel syndrome (`(Tarsal tunnel syndrome)`).
Tests for sinusitis
Your doctor may also do some imaging tests to take pictures of the ankle and surrounding area:
- Foot X-ray.
- MRI (Magnetic Resonance Imaging) test.
- CT scan (`(CT scan - Computed Tomography scan)`).
How is Sinus Tarsi Syndrome treated?
Your doctor will recommend treatments to reduce swelling and pain in your sinuses. The most commonly used treatments are:
- Over-the-counter (OTC) pain relievers: You can use nonsteroidal anti-inflammatory drugs (NSAIDs) or acetaminophen (paracetamol) to reduce swelling and pain. However, do not take these medications for more than 10 days without medical advice.
- Corticosteroids: These are powerful anti-inflammatory medications prescribed by a doctor. Your doctor may also inject cortisone directly into your subtalar joint.
- Immobilization: You may need to wear an ankle brace or a special walking boot to keep your ankle immobile and safe while it heals. Your doctor may also suggest taping your ankle for extra support. They will teach you how to do this safely.
- Physical therapy: A physical therapist will teach you exercises and stretches to strengthen the muscles around your ankle. They will help you regain your ankle's range of motion (how far you can move your ankle).
- Orthotics: Orthotics are special inserts that are placed inside your shoes. You can buy them from a pharmacy, or you can have them custom-made for you. Your doctor will tell you what kind you need and how long you need to wear them. They may also recommend shoes that support your feet and ankles (or that you should avoid wearing certain types of shoes).
- Surgery:Surgery is rarely necessary for sinus tarsi syndrome. A doctor will only consider surgery if other treatments have not helped, or if you have persistent severe pain or swelling. If so, they will explain to you what type of surgery you will have and what to expect afterward.
Can Sinus Tarsi Syndrome be completely cured?
Yes, most of the time, sinusitis syndrome will resolve once you find a treatment that can control your symptoms. As the swelling in the sinuses decreases, the pain will also go away.
Sinus tarsi syndrome caused by an ankle sprain usually improves gradually as the sprain heals. It can usually take about a month for a sprained ankle to heal.
However, if your sinusitis is caused by a change in the natural position of your feet or another health condition, it may take longer to heal. Ask your doctor or a podiatrist about this.
How can you protect yourself from this situation?
It may not be possible to completely protect yourself from sinus tarsi syndrome, especially if you are an athlete. But there are ways to reduce your risk.
When playing sports or during physical activity:
- Wear the correct safety gear (including the right type of shoes).
- If your ankle hurts during or after physical activity, don't "play through the pain."
- Give your ankles time to rest and recover after strenuous activity.
- Warm up and stretch before playing sports or exercising.
- Cool down and stretch after physical activity.
Remember these things to protect yourself from accidents:
- Keep your home and workplace tidy and free of clutter.
- When reaching for something high up in the house , always use appropriate equipment (e.g., a ladder). Do not climb on chairs, tables, or counters.
- If you have difficulty walking or are at high risk of falling, use a cane or walker.
When should I see a doctor?
If you have an injury and are experiencing symptoms of sinusitis syndrome, see a doctor. If your symptoms do not improve after a few days of treatment (or if they get worse), tell your doctor.
When should I go to an emergency room (ER)?
If you have any of these symptoms, go to the emergency room immediately:
- Very severe pain.
- If the swelling is getting worse.
- Color change (e.g. turning blue, turning black).
- If you can't move your foot or ankle at all.
What questions should I ask my doctor?
You can ask the doctor these questions:
- Do I have sinus tarsi syndrome, or is it some other ankle problem?
- Did I sprain my ankle? Is that what caused the sinus tarsi syndrome?
- Will I have to do any tests?
- What treatment do you suggest to control the pain and swelling?
- How long should I avoid physical activity?
The sinus tarsi is a small space in your ankle that can be very painful if irritated. Sinus tarsi syndrome occurs when the small space between the ankle bone and the heel bone becomes swollen due to an injury or other problem. Ankle sprains are often the cause.
Take-Home Message
If you have ankle pain and difficulty moving or using your foot or ankle—especially if you know you've slipped, rolled, or sprained your ankle—it's important to see a doctor or podiatrist. They can help you determine the cause of your symptoms and explain what you can do to help your ankle. Sinus tarsi syndrome can be a very uncomfortable condition, but it's usually a temporary problem. Once your ankle heals and the swelling goes down, you should be able to return to your normal activities. So, the most important thing is to not panic and get proper treatment.
👩🏽⚕️ Additional questions (FAQs)
💬 Is Sinus Tarsi Syndrome the same as ankle sprain?
A bone is not broken! On the outside of our ankle, there is a small tunnel/slot-like gap between two bones. It is called the 'Sinus Tarsi'. This is a condition where the leg suddenly twists while you are walking (Ankle sprain) and the tissues, ligaments, and nerves inside that tunnel become severely injured, swollen, and painful for a long time.
💬 How do I know if the pain in my ankle is Sinus Tarsi Syndrome?
The main symptom is a constant, severe pain on the 'outer side' of the ankle. The pain becomes unbearable, especially when walking on uneven ground with stones or on a grassy field. It feels like the leg is unstable/will roll over when the leg is on the ground, and it also hurts when you touch it.
💬 If your leg is twisted and looks like this, what is the best treatment for it?
First, you need to put ice packs and take NSAIDs (ibuprofen) to reduce the swelling in that space. Then, you definitely need to do physiotherapy and train your balance. If it still bothers you, the doctor will inject a 'Corticosteroid injection' into that space (Sinus Tarsi) to reduce the swelling 100% and heal the leg completely.
