What are potential causes of medial ankle pain?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Medial ankle pain—discomfort on the inside of the ankle—is most commonly caused by injury or strain to the deltoid ligament, ankle instability from previous sprains, or dysfunction in the tendons supporting the foot and ankle (such as the posterior tibial tendon). Less commonly, it may signal stress fractures, arthritis, or nerve compression like tarsal tunnel syndrome.

Because medial ankle pain has many possible causes—some minor, some requiring prompt care—identifying the likely source early can help you avoid worsening damage and get the right treatment faster. Take a free, instant, online symptom check to better understand what may be causing your pain and confidently plan your next steps.

Explanation

Medial ankle pain is a common issue and can have several causes. One potential cause is problems with the deltoid ligament, which is a key structure on the inner side of the ankle that helps keep it stable. If this ligament is injured or strained, it can lead to pain.

Another cause of medial ankle pain is medial ankle instability. This happens when the structures that support the ankle are not strong enough, leading to the ankle feeling wobbly or giving out. This instability can cause discomfort and pain on the inner side of the ankle.

Additionally, tendinopathies, or problems with the tendons around the foot and ankle, can also lead to medial ankle pain. Tendons connect muscles to bones and can become irritated or inflamed, causing pain and discomfort. If you're experiencing any of these symptoms, you can check your symptoms to better understand what might be causing your discomfort and when to seek medical care.
