Tendonitis

What is tendonitis?

Tendons attach muscles to bones. Tendonitis develops slowly and is caused by overworking the tendons. Tiny tears occur on a tendon when it is constantly overworked. The tendon becomes irritated which causes swelling, heat, redness, and pain.

What is the cause?

The most common cause of tendonitis is increasing the length of time or intensity of an activity or exercise program too quickly. Tendonitis in the knee, foot, and calf are common in athletes who do sports that involve running and jumping. Tendonitis in the knees can also occur from biking. Swimming, swinging a golf club, or pitching a ball can cause tendonitis in the shoulder. Wearing worn-out shoes, poor conditioning, or training mistakes are other possible causes.


Body structure problems like having bowlegs, one leg shorter than the other, or flat feet can also cause tendonitis. Tendonitis may also occur from repeated motion such as typing or using a hammer.

What is the treatment?

Often people try to stand the pain and do nothing. They hope that it will simply go away. Sadly, more serious symptoms may begin if these early symptoms are ignored. The occasional pain will change to constant aching, pain, and stiffness before, during, and after exercise. The tendon will also hurt when the area is touched.


If you are having pain:

  • Stop the activity that is causing the problem for a short time.
  • Ice the area for 5 to 10 minutes every 3 or 4 hours. The best way to do this is to freeze water in a paper cup, peal part of the cup away, and rub the ice directly on the injured area. Don't leave ice directly on the skin for longer than 10 minutes at a time.

You can keep doing activities that do not stress or cause pain to the injured area. Make sure to stretch before doing any activities. Also, you may need to cross train. That is, instead of doing only one sport, try different activities to prevent overuse injuries.


Take anti-inflammatory medicines as approved by your health care provider. See your provider if the problem does not go away in a couple of weeks. Irritated tendons can tear if left untreated. When this happens more serious treatment such as a wearing a cast or surgery is needed.

How can I prevent tendonitis?

  • When you exercise, wear shoes that fit right and are made for the activity.
  • Gently stretch before and after exercising.
  • Use proper form and posture during your activities, whether they are sports or job-related. For instance, be sure your tennis stroke is correct and that your tennis racket has the proper grip size.
  • Warm up before exercising or doing other activities.
  • Ice any stiff or sore joints after exercise or work.
