Tendonitis is inflammation in a tendon, which is the tissue that connects muscle to the bone. This condition causes pain or feelings of tenderness primarily around joints such as the knee, foot, elbow and shoulder.
Recent studies indicate that chronic pain associated with a physical injury may be influenced by stress and emotional issues. In addition, several studies have found that 15-30% of patients with chronic pain also suffer from post-traumatic stress disorder (PTSD).
When your shoulder hurts, even the simplest daily tasks can be excruciating, such as driving a car or washing dishes. If you are an active person, you may be unable to enjoy your hobbies and outdoor activities.
