You can partially or fully tear your Achilles tendon. What it feels like depends upon the severity of the tear. A torn or ruptured Achilles tendon is a condition that needs immediate medical attention. Although the Achilles is one of the strongest and the largest tendons in the body, it is vulnerable to injury.

Identification

The Achilles tendon is located on the back of the ankle. It connects the heel bone (calcaneus) to the muscles of the lower leg. If you touch it, it feels like a thick cord. Under normal conditions, and when you squeeze it, there should be no pain or tenderness.

Partial Tear Symptoms

A partial tear will ache and feel sore. It will probably worsen with activity and definitely hurt during exercise. It will be tender to the touch, and if you squeeze the tendon, there will be pain. You may also have swelling or pain when you rise up on your toes. Even a sore heel can result from a torn tendon.

Full Tear Symptoms

A full tear will feel like you have been punched, hit or kicked in the back of the lower leg. There may be a loud "pop" at the time of rupture. Also, pain will be immediate and intense, then it will usually subside quickly. Rising up on your toes with a full rupture is impossible.

Other Conditions

Your Achilles tendon is also prone to tendonitis, which is inflammation. This can occur from too much repetitive activity like running or jumping. Your ankle and heel will feel sore, may burn and be warm to touch. The tendon can also get bursitis if the protective coating becomes irritated and overstretched.

Pain Management

Seek medical attention to diagnose your Achilles tendon problem. You can apply ice to reduce swelling and burning pain. A complete tear needs complete rest and may require surgery for full repair. For bursitis, application of heat and using heel lifts in your shoes is recommended.
