Foot tendonitis is inflammation in any of the tendons in your foot. The most common are the Achilles, peroneal, extensor and posterior tibial tendons. An irritated foot tendon is usually the result of overuse and can lead to pain and swelling.
Achilles tendonitis: Affects the tendon connecting your calf muscle and heel bone. This tendon is the strongest tendon in the body. It helps us run, jump, walk and do other activities that require us to rise up on our toes.
Extensor tendonitis: Irritation of the tendon that runs along the top of your foot. These tendons attach bones at the front of your leg to your toes.
Peroneal tendonitis: Inflammation in either of the two tendons that run along your outer ankle bone. They connect to your midfoot and your arch to help with stability.
Posterior tibial tendonitis: Affects the tendon that connects your calf muscle to bones on the inside of your foot. These tendons help hold up the arch of your foot.
Plantar fasciitis: Pain at the underside of your heel and within the arch of your foot. While this is technically not a tendon but a ligament, it can produce the same type of painful conditions that present like tendonitis, with similar treatment approaches.
