Most info on tendons covers athletic injuries (RICE), verses damage from inflammation and drug side effects. This was the only book I could find that covered damage to tendons that was not related to athletic injury. My tendon stiffness, to the point of discomfort, was related to drug side effects and I found the information in Michelle Cook's book to be excellent. I have tried some of the natural remedies and they have helped. The author has a deep understanding of how muscles and tendons work or don't work when they are exposed to inflammation. Some remedies I was familiar with; others not. However, this book really added to my knowledge of how muscles and tendons function and what they need to remain healthy.
