Tendonitis is inflammation of a tendon; “itis” after a word usually indicates inflammation, think of arthritis, cellulitis, and so on. Inflammation can be from injury or disease. Healthcare providers prefer to use the word “tendonopathy” to show that tendonitis is more than only inflammation. It is also thought to be a degenerative disease of connective tissue.
There are many reasons a person can be susceptible to inflammation, including an inborn (hereditary) tendency, diabetes or a high sugar diet and high anxiety.
