Tendinitis

Tendonitis (tendinitis) is the inflammation or irritation of a tendon that makes it swell. Tendons are strands of connective tissue between muscles and bones that help you move. This condition usually happens after a repetitive strain or overuse injury. It’s common in your shoulders, elbows and knees. If you have tendonitis, you’ll feel pain and soreness around your affected joint, usually near where the tendon attaches to the bone. Tendonitis can be either acute (short-term) or chronic (long-term).

Types of tendonitis

Types of tendonitis get their names after sports and the area of your body where injuries happen. Some of the most common types of tendonitis include:

• Tennis elbow.
• Golfer’s elbow.
• Pitcher’s shoulder.
• Swimmer’s shoulder.
• Runner’s knee (jumper’s knee).

How common is it?

Tendonitis is a relatively common condition. This is because people participate in occupations, activities or hobbies where they can easily overuse or injure their tendons.
