Achilles Tendinitis is the inflammation of the tendon that connects the calf muscle to the heel bone. This tendon is used when you walk, run or jump and therefore, can withstand great stress. When repetitive stress is placed on the tendon, tendinitis can occur. There are two types of achilles tendinitis, depending on where it occurs. When the middle portion of the tendon begins to degenerate, that is non-insertional Achilles tendinitis. When the tendinitis involves the lower portion of the heel, where the tendon attaches to the heel bone, it is insertional Achilles tendinitis.
Achilles tendinitis results from repetitive stress to the tendon such as a sudden increase in the amount or intensity of exercise activity. Achilles tendinitis will result in the pain and stiffness in the back of the leg after running or exercising.
If ignored Achilles tendinitis can lead to tendon tearing or rupturing, and therefore, it is important to treat it when it occurs.
