7Bone Spur
A bone spur occurs when an extra bone grows in the area where your Achilles tendon connects with the heel bone. As a result, this part would rub against your tendon and lead to inflammation over time. The main cause of a bone spur is the damage to joints related to osteoarthritis. Most cases cause no noticeable symptoms and would go undiagnosed for many years. In mind cases, treatments are not necessary, depending on their effects and the locations of the spurs. But when it rubs on your Achilles tendon and causes tendinitis, medical attention is needed to prevent further complications.[7]
