Because it’s probably tendinosis. Often, chronic tendonitis (also spelled tendinitis), which lasts more than 6 weeks is really tendinosis (also spelled tendonosis). The difference is that acute, short-term tendinitis is thought to be caused by inflammation, which is an active immune response of the body to a perceived threat. The acute, inflammatory tendonitis can be treated and usually resolved within several weeks by icing the area 3 to 4 times daily for 20-30 minutes, resting, and taking over-the-counter or prescription strength anti-inflammatory medication, such as ibuprofen.
Chronic tendonitis is usually defined by the tendon pain lasting more than 6 weeks, and the condition is more accurately referred to as tendinosis. Tendinosis is mainly caused by degeneration of the tendon. In order to effectively treat and resolve tendinosis, you must stimulate regeneration of the affected tendon. There are very few approaches that do this. Astym treatment has been used successfully for years and is the most established treatment to stimulate regeneration of a tendon and other soft tissues.
