Fibrocartilaginous metaplasia of the tendon
Pain-free
Formative phase
characterized by cell-mediated<unk>  deposits
+/- Shoulder pain
Resting phase
lacks inflammation or vascular infiltration
+/- pain
Resorptive phase (1-2 wks)
characterized by phagocytic resorption and vascular infiltration
most painful phase
Sudden onset of severe pain, usually at rest, worse at night
