Connective tissues can become sore and sometimes unusable from repeated exposure to micro-trauma.
Because of the slow onset of symptoms, people sometimes ignore the condition until the symptoms become chronic and permanent injury occurs. The best way to visualize RMI is to think of each of your joints as a bucket. Micro-trauma from a variety of activities drips into your joint's trauma bucket. Fortunately, your body can heal with time and safely absorb a certain amount of trauma. But if more trauma is placed into the bucket than can be absorbed by the natural healing process, the result can be pain and impaired movement.
