Peroneal Tenosynovitis Runners

Peroneal tenosynovitis may sound complicated, but for runners, the signs are often easy to spot. This condition affects the tendons along the outside of the ankle — the ones that help stabilize your foot with every stride. When these tendons become irritated or inflamed, runners often notice pain, swelling, or stiffness that gradually worsens with training. Early signs include a dull ache or soreness at the outer ankle, sometimes turning into sharper pain during or after runs. Swelling, warmth, or even a snapping sensation near the ankle can also appear. Many runners feel stiffness first thing in the morning or after sitting for long periods. On trails or uneven ground, the ankle may even feel weak or unstable, making balance harder to maintain. Unlike an ankle sprain, which happens suddenly, peroneal tenosynovitis usually builds up over time due to repetitive stress, higher mileage, or uneven terrain. Recognizing these early warning signs can help runners better understand what their body is saying and stay consistent in their training. Looking to get in touch with our office?
