Tendinitis and bursitis
What is tendinitis ?
Tendinitis or tendonitis is the inflammation of a tendon or of the protective sheath that surrounds it. A tendon is a fibrous connective tissue that connects muscles to your bones. Inflammation of the tendon is in most cases caused by overuse of the tendon or by an infection.
Symptoms of tendinitis can vary from mild pain and irritation to chronic pain and discomfort. Possible symptoms are :
- pain when tendon is solicited with strength
- restriction of mouvement, with or without pain
- affected region is tender and painful when touched or moved
- burning sensation in the affected area
- swelling, redness, tightness and burning in the affected.
What is bursitis ?
Bursitis is the inflammation of the bursa located between tendons and bones. Bursae are fluid-filled sacs that allow tendons to move soothly without friction on the bone. They are located in the shoulders, elbows, wrists, buttocks, knees and ankles. . Excessive effort or overuse of the joint can lead to thickening of tendons, friction on the bursae and inflammation.
Symptoms of bursitis are directly linked to the severity of the inflammation and can resemble those of tendinitis. The most common symptoms in the enflamed area are :
- pain and sensitivity
- redness and heat
- swelling near the bursa
- increase in pain after an activity
- pain that can be felt beyond the irritated area
- morning and late day stiffness.
Tendinitis, bursitis and decrease in collagen
The tendons, these tissues that link muscles to bones are primarily composed of collagen. Collagen is what maintains their structure and strength. They support and stabilize joints. Ligaments are also composed of fibrous tissues rich in collagen linking bones together. They ensure optimal mobility of joints. À lack of collagen production can weaken ligaments which in turn facilitates wrong movements and predisposes to tissu damage and injury.
