Cause #3: Tendonitis
Tendons are the tough, sinewy ‘strings’ that attach our muscles to our bones. They work by allowing the muscles to pull on the bones and other body parts, causing them to move. This means that they need to be strong enough to be able to withstand a lot of pulling, but they are not impervious.
Tendonitis is a condition where the tendons in the body become inflamed. This can cause them to become sore and they can affect any part of the body, including the tendons in the feet. Medications are available that will help relieve the symptoms and surgery may be required in some cases.
