How to heal peroneal tendonitis

The peroneal tendons run along the outer side of the lower leg and ankle, helping control foot position and ankle stability. Repeated running, uneven ground, a change in training, or an ankle injury can overload them. Pain may sit behind or below the outer ankle and can worsen with walking, turning the foot, or pushing off. Tendon pain can resemble muscle soreness after exercise, but persistent focal pain needs a closer examination.

Temporarily reduce hills, running, jumping, and uneven-surface activity if they reproduce symptoms. Supportive footwear and an ankle brace may make walking more comfortable. Use cold or warmth according to which feels better, protecting the skin. Once daily walking is easier, rehabilitation may include ankle range-of-motion work, calf raises, balance practice, and resistance exercises. Progress one change at a time, monitoring how the ankle feels during activity and later that day. Physiotherapy can tailor loading and check foot and ankle mechanics. Shockwave therapy or PRP injection may be discussed in selected persistent cases, after diagnosis and a review of alternatives.

Seek prompt assessment after a sudden snap, rapid swelling, inability to bear weight, or an ankle that feels unstable. Review is also sensible when pain follows an ankle twist, keeps returning, or does not improve with activity modification. Urgent care is appropriate for severe pain with numbness, a cold or discoloured foot, or a visible tendon deformity.

Ask whether the tendon is irritated or torn, whether imaging is needed, which brace or shoe is suitable, and how to progress strengthening without a flare.
