Tendons are tough fibers that connect muscle to bone.
Tendinopathy is an injury to the tendon. It can cause pain and swelling and make it difficult to move. Tendinopathy may be: Tendonitis—inflammation of the tendonTendinosis—tiny tears in the tendon with no major inflammation
The Achilles tendon connects the calf muscle at the heel bone. An achilles tendinopathy is pain in this tendon.

Tendinopathy is most often caused by overuse of a muscle and tendon. Over time, the regular strain on the tendon causes the structure of the tendon to change.
Overuse of the achilles tendon can happen with: Increasing your speed or running long distances too quicklySuddenly adding strenuous hills or stair climbing to your exercise routineDoing too much too soon after taking time away from exercisingA sudden or violent contraction of the calf muscles, such as during an all-out sprintRunning too much
Achilles tendinopathy is more common in older adults due to the aging process. Other factors that may increase your risk of getting achilles tendinopathy include: Improper or badly worn footwearLack of flexibility of the calf musclesAn improper training program—such as increasing intensity too quickly
Symptoms of tendinopathy may include: Tenderness—usually just above the heel bone and often more noticeable in the morningStiffness that gradually eases as the tendon is warmed-upPain after activity that gradually worsensPain along the tendon during and/or after runningSwelling in the area of the Achilles tendonPain at the back of the ankle
You will be asked about your symptoms and exercise habits. A physical exam will be done and the doctor will check the motion of your ankle.
A diagnosis will be made based on the exam and history.
If more damage is suspected or the diagnosis is unclear the doctor may order imaging tests. Tests may include x-rays, ultrasound, or MRI scan.
Tendinopathy may take weeks or months to fully heal. Treatments include:
Full rest is usually not needed. Tendons do need a break from activities that are causing pain. A gradual return to normal activity will decrease the chance of damaging the tendon again.
Other supportive steps may include, icing the area, shoe inserts, or ankle taping. Prescription or over-the-counter medications may be advised to reduce pain.
A physical therapist will assess the tendon. Ultrasound and/or massage may be done to help relieve tension.
An exercise program will be created to strengthen and stretch the calf muscles. This can help with recovery and in preventing future injuries.
To decrease your chances of getting Achilles tendonitis: Wear appropriate footwear for your sport.
Replace footwear that shows signs of wear.
Gradually add hill work, stairs, speed, and distance to your routine.Stretch
and strengthen the calf muscles regularly.
