Tendonitis has a very low rate of self-healing if left untreated. The main reason is that once an acute attack of tendonitis is not treated promptly and regularly, it can easily progress to a chronic inflammatory response, with recurrent symptoms such as pain and swelling later on, which can seriously affect the quality of life. The correct management of tendonitis should be prompt and standardised treatment in the acute phase to completely cure the inflammation and avoid recurrence.
