Post-Tib Tendonitis

Posterior Tibial Tendonitis is a common ankle problem that can cause pain on the inner side of the foot and ankle.

Symptoms, Causes and Common Treatments

Post-Tib Tendonitis


  • Heel pain
  • Arch pain
  • Plantar fasciitis
  • Heel spurs
  • With post-tib tendonitis, pain is more severe when on your feet–especially when walking or running.


Also known as “Post-Tib Tendonitis,” Posterior Tibial Tendonitis occurs when the muscle is overused and the tendon (soft tissue) that connects the muscle to your bone is strained. With Posterior Tibial Tendonitis, the tendon does not function to hold up the arch, resulting in flat feet. Years of over-pronation (flat feet) can also lead to posterior tibial tendon dysfunction. If you keep overusing the muscle, damage to the tendon builds up and tendonitis develops. At first the pain or swelling may come and go quickly, but eventually the problem may become more permanent.

Common Treatments

  • Wear shoes that provide cushioning, support and shock absorption
  • Use arch supports with sufficient support that are constructed from shock absorbing, cushioning materials.
  • Vary exercise routines. The variety will keep one set of muscles from being under continuous stress.
  • To address post-tib tendonitis, you can reduce your symptoms by limiting activity to control the pain and swelling. Stay off your feet a few days, and then slowly increase your activity. Rest allows the tissues in your foot to heal.
