The physical symptoms of damage to the tendon, or tendinopathy, are swelling, tenderness, warmth and pain in the area around the tendon, according to WebMD. The pain worsens when the patient tries to use the tendon and it radiates out from the joint the tendon supports.
The tendon can also produce a crunching sound when the patient tries to use it, according to WebMD. Pain or discomfort often accompanies this sound. The tendon is stiff as well as painful, and this discomfort is worse at night and first thing in the morning. The joint served by the tendon is also stiff.
In some cases, inflammation due to calcium crystals causes the pain of a damaged tendon, says WebMD. This is called calcific tendinitis, and medical experts do not know what causes it.
The tendons most likely to suffer damage are those that support the ankle, the shoulder, hip, knee and wrist, says WebMD. The elbow is also at higher risk for tendinopathy. Tendon injuries usually happen because of wear and tear and aging.
A tendon is a type of connective tissue that attaches a muscle to a bone and helps them move. A ligament is connective tissue that connects a bone to another bone and keeps them stable.
