I've had a frozen shoulder twice. I did go to physical therapy which helped a great deal. My physical therapist gave me exercises to do at home. I did them religiously and my shoulders eventually returned to normal range of motion. The exercise that seemed to help the most was walking my fingers up the wall (actually used a door frame). I taped the highest place that I could reach and tried to go beyond that every day. I never had any shots or medication for my shoulder. The P/T and home exercises worked for me. Good luck with yours, Charlee.
