TBH I couldn't tell what the condition was or what general kind of treatment it was from the article without making big assumptions. Chronic pain is a symptom, viz. pain that doesn't go away after a short time. What was your disease? Or was it never given a name but the pain was treated?

Then I had to click a link "a landmark study" to get an idea of what the treatment is. Why not put the title of the treatment there?

Finally, that article is about back pain. But you had tendon pain. Obviously a psychological technique can be applied to multiple diseases, but you might say something about that.
