Swollen malleolus: causes, symptoms, and remedies

The malleolus is the bone on the inside and outside of each ankle that provides stability to the ankle joint. When the tissues become inflamed or fluid accumulates, a swollen malleolus can cause pain and limit mobility. While it is a common problem and often linked to injuries such as ankle sprains, it can also be a symptom of more serious conditions that require medical attention. Joint conditions such as arthritis or tendonitis can inflame the area and worsen the condition. Circulatory problems, such as venous insufficiency, are also a common cause of persistent malleolar swelling.

Symptoms and causes of swollen ankle

A swollen malleolus presents with obvious symptoms. Ankle pain can be intermittent or continuous and vary in intensity, but is often associated with swelling, stiffness, redness, and heat. It particularly affects runners, who can overwork their muscles, tendons, and ligaments.

This condition can affect the internal (medial) or external (lateral) malleolus, and in more severe cases, swelling can completely impede ankle mobility, making it difficult to walk or maintain posture. The pain can have various causes, such as trauma, injury, sprains, joint instability, arthritis, gout, tendonitis , bone fracture, or nerve compression.

Treatment of swollen ankle

In most cases, a swollen malleolus heals with self-care. Treatment depends on the underlying cause. In cases of trauma, rest and ice application help reduce swelling and acute inflammation, relieving pain. 

If the ankle swells, it is advisable to avoid standing for long periods and to raise the ankle above the pelvis to promote venous return and drainage of fluids trapped in the leg.

When the malleolus is swollen, over-the-counter pain relievers and anti-inflammatory medications help manage the inflammation, while physical therapy helps restore full ankle function. If the problem is caused by a fracture or a chronic condition, surgery or specialized treatment may be necessary.

Possible complications associated with the malleolus

A swollen malleolus, if not properly treated, can lead to significant complications, such as permanent joint damage, chronic limited movement, and balance problems. For this reason, it's essential to undergo an orthopedic examination to understand the cause of the pain and make an accurate diagnosis so the problem can be addressed promptly. If symptoms persist or the condition worsens, the orthopedic doctor may order an X-ray or MRI to assess the presence of a possible lesion.
