Tendons are flexible bands of tissue that connect muscles to bones. They help your muscles move your bones. Tendinitis is the severe swelling of a tendon. Tendinitis is inflammation of a tendon caused by overuse or injury of a tendon. It causes pain and soreness around a joint. Tendinitis can occur at any age but are more common in older individuals due to the loss of elasticity and overall structure. There are several types of tendinitis in the foot and ankle but the two most common are: Achilles tendinitis, posterior tibial tendinitis. (Refer to their pages)
Tendinitis depending on its severity and location can be treated with a variety of stretching/exercises, injections, orthotics, and even surgery.
Tendonosis is similar to tendinitis and is sometimes referred to chronic tendinitis. Tendonosis is the breakdown of the tendons at the cellular level without any obvious inflammation.
