4 weeks after surgery.  My shoulder finally loosened up and less pain, finally got about 6 hours sleep.  Not wearing my sling as much and I think that alone helped loosen things up.  Still have to be very careful not to fall.  Went to PT yesterday and now back to pain and less sleep, but the PT is necessary. A pain pill before PT helps a little.  Home exercises is a must.  Keep you posted, good luck to all and try to keep your spirits up!
