Frozen    shoulder    (adhesive    capsulitis)    is    stiffness,    pain    and limited   range   of   movement   in   your   shoulder   that   may   follow an    injury.    The    joint    capsule    and    tissues    around    the    joint stiffen,   scar   tissue   forms,   and   shoulder   movements   become difficult and painful. Frozen   shoulder   can   develop   when   you   stop   using   the   joint normally     because     of     pain,     injury,     or     a     chronic     health condition,   such   as   diabetes   or   arthritis.   Any   shoulder   problem can   lead   to   frozen   shoulder   if   you   do   not   work   to   maintain full range of motion. Frozen shoulder occurs: • After surgery or injury. • Most often in people 40 to 70 years old. • More    often    in    women    (especially    in    postmenopausal women) than men. • Most often in people with chronic diseases.
