How Tendon Inflammation Can Cause Tendonitis


A tendon is a tough but flexible band of fibrous tissue. A tendon is a structure in your body that connects muscle to bone. The tendons are very organized. The body creates very densely packed collagen fibers in parallel matrices that are flexible but very strong. The strength of the tendons is important as these dense structures must withstand very heavy loads.

The skeletal muscles in your body are responsible for joint movement, allowing you to walk, jump, lift weights, and move in many different ways. When a muscle contracts, it pulls on the bone and causes this movement. The structure that transfers the force of contraction from a muscle to a bone is called a tendon. In the case of the eyeball, the tendons attach the muscles to this structure and not to the bone, allowing the muscles to move the eye. There are about 4,000 tendons in your body .

Tendons vs. Ligaments

Although both ligaments and tendons are made of fibrous connective tissue (collagen), ligaments link bone to bone rather than muscle to bone. Ligaments hold structures together, such as joints.


Certain tendons are prone to tendonitis , a problem in which the tendon becomes irritated and inflamed. It causes pain when a muscle or bone is moved. Tendonitis can develop as a result of overexertion from repetitive movements or be caused by stress or injury to a muscle or joint.

Tendonitis often occurs due to work or sports, but it can happen to anyone. Your risk of tendonitis increases with age. Tendinitis develops due to a violation of the blood supply to the tendon. Certain " dividing " tendons are prone to tendonitis. This includes:

  • Achilles tendon : This tendon attaches the calf muscle to the heel bone. If it is overstretched, it can be fully or partially broken, often with a popping sound and a sharp pain in the back of the ankle and leg. Surgery or nonsurgical treatment may be required.
  • Rotator cuff tendon : The rotator cuff tendons attach muscles to the shoulder joint. You can develop tendinitis from injury, repeated lifting, or playing sports that use your arms above your head.
  • Posterior tibial tendon: This tendon attaches the calf muscle to the bones inside the foot, supporting the arch of the foot and supporting the foot as you walk. You can be injured if you fall or if it is used repeatedly in heavy sports such as basketball, tennis, or soccer.
  • Short radial extensor wrist : This is an inflammation of the tendon, often called "tennis elbow," that connects the muscles of the forearm to the elbow. This is due to many activities, including racquet sports such as tennis.
  • Patellar tendon – A common occurrence in jumping sports such as basketball and volleyball, the “ jumper's knee '' involves repetitive stress on the patellar tendon, which connects the patella (kneecap) to the tibia (tibia) and assists you to extend the pimple.

Symptoms of tendonitis include pain, tenderness, and slight swelling. Stopping pain-causing activities for a few days can help resolve minor cases, but if they persist, you should see your doctor. You may need to learn how to prevent recurrence using proper and alternative methods.
