What muscles could cause inner ankle pain?

Muscles that may contribute to inner ankle pain include tibialis posterior, flexor digitorum longus, flexor hallucis longus. Trigger points, strains, or weakness in these muscles can refer pain to this area.

Q: What causes pain in the inner ankle?

Common causes of inner ankle pain include posterior tibial tendon dysfunction causing flat foot, medial ankle sprain (eversion injury), tarsal tunnel syndrome compressing the tibial nerve, deltoid ligament strain, tibialis posterior tendinitis from overpronation. The specific cause depends on the nature of the pain, how it started, and which movements aggravate it.

Pain on the inner (medial) ankle involves the tibialis posterior tendon, the deltoid ligament, and the flexor tendons passing behind the medial malleolus. It is common in flat-footed individuals and those who overpronate during walking or running.

Muscles in This Area

Lower Leg

tibialis posterior

Hidden deep in the calf behind the tibia, the tibialis posterior supports your arch and stabilizes the ankle. It inverts the foot and assists plantarflexion, vital for push-off in running and preventing flat feet. Weakness leads to overpronation and foot pain during activity.

Lower Leg

flexor digitorum longus

The flexor digitorum longus is a powerful muscle in the deep posterior compartment of the lower leg, running from the tibia down to the toes. It flexes the four smaller toes and assists in plantarflexion at the ankle, helping with push-off during walking, running, and jumping. Strong flexors like this are crucial for balance, propulsion, and preventing foot drop in athletes.

Lower Leg

flexor hallucis longus

Running deep in the calf's posterior compartment, the flexor hallucis longus flexes the big toe and plantarflexes the ankle. It's essential for powerful push-off in sprinting, ballet, and hill running. Athletes rely on it for toe grip on uneven terrain.

When to See a Doctor

Seek medical attention if the arch of the foot is collapsing, you have numbness or tingling on the bottom of the foot, the inner ankle is significantly swollen, or if walking becomes progressively more painful.
