What else could the pain be?
An inversion injury, where you roll over your ankle can cause an ankle sprain. This usually causes immediate pain, some swelling and even bruising.
If the posterior tibial nerve gets impinged in the tarsal tunnel it can cause tingling, numbness and pain into the foot.
Repeated ankle sprains and poor biomechanics can cause inflammation of the structures around the ankle which leads to stiffness, difficulty walking on uneven ground and chronic pain on the outside of the ankle.
Nerve root compression from the lower back can cause pain, pins and needles, numbness and weakness down the leg and into the ankle.
- Superior tibiofibular joint
Knee injuries can influence the joint which can lead to pain at the outside of the ankle.
Excessive training can cause stress fracture of the talus, which will cause a gradual onset of pain on the outside of the ankle that is worsened by weight bearing and running.
- Complex Regional Pain Syndrome (CRPS)
Repeat injuries with chronic ankle pain may cause a change in the nerves, central sensitization. This will cause symptoms of temperature change, flaky skin, swelling without reason and stiffness.
- Avulsion fracture of the base of the 5th metatarsal
If not responsibly treated your peroneus tendonitis may lead to an avulsion fracture, which means the tendon pull is too strong for the attachment site and a muscle contraction causes the bone to break away with the tendon.
When a small piece of bone breaks away, together with the peroneus brevis tendon, from the 5th metatarsal you will have swelling, pain and bruising along the outside of the foot. You may limp when walking due to the pain.
