See A Specialist: If you have not done so already, you should see a specialist for diagnosis and treatment. Sports medicine doctors and physiatrists are often good choices for chronic tendon injuries, and they will likely refer you to a physical therapist. A rheumatologist and/or a functional medicine doctor can also be helpful. You can use websites like this one to learn more about your injury and treatments for it, and that knowledge will help you work with your doctor to design a program tailored to your specific case.
Get A Diagnosis: Diagnosis of tendinopathy is usually made through evaluation of medical history and symptoms, a physical exam, and imaging with MRI or ultrasound. If you have tendinopathy in multiple areas, make sure you don't have a collagen disorder like Ehlers Danlos Syndrome, or an inflammatory condition like ankylosing spondylitis, or an autoimmune issue.
Stay Informed: Read about new research into tendinopathy treatments and general health. Some doctors are more up-to-date on the research than others, so arming yourself with information is helpful. Medicine in general tends to be better at treating acute issues than chronic ones; you'll need to take an active role in your care to get the best results.
Paratenonitis refers to inflammation of a thin sheath of tissue called the paratenon that surrounds some tendons, such as the Achilles.
Tenosynovitis refers to inflammation of the synovial sheath that surrounds some tendons, such as the flexor tendons in the hands..
Chronic injuries occur slowly over time and persist, as opposed to acute injuries that occur suddenly, such as tendon ruptures (partial or complete).
