This question comes up a lot for runners with Achilles tendon injuries. But it can happen with any kind of tendon. The difference between an injury to a tendon which has been labeled "tendonitis" versus "tendinosis" is really a difference in the amount of time that you have the condition and the amount of damage to the tendon itself.

 There’s been a long running debate about this. I was lecturing at a medical conference in Iceland this the summer. Specifically, it was a lecture on tendon injuries in athletes. One of the key points was that the old research claims inflammation does not play a role in the development of tendinosis is wrong.

 In this episode I will explain the difference between tendonitis and tendinosis.
