Not Bursitis - Frozen Shoulder

Yesterday I went to the orthopedist about my left shoulder. We have had some luck with physical therapy - but I'm not making much progress in some ranges of motion. In my perspective, I got the worst possible trwatment plan - every day - at least once an hour, move my arm into the area of pain. Do not stop at discomfort - it must really HURT. Does he think I'm insane? And it will take quite a while for it to be fixed. Here is a treatment note from the AARP website (I know, I know):

Treatment involves non-steroidal anti-inflammatory medications (NSAIDs), steroid injections, and physical therapy. It can take as long as 12-18 months to see improvement. The physical therapy is intense and needs to be done every day. Steroid injections can significantly improve the results of physical therapy.
If therapy is not successful, or if a patient can not tolerate therapy, a shoulder manipulation may be performed. This procedure is done under anesthesia. The health care provider will forcibly bring the shoulder through a range of motion to release the scar tissue.
Arthroscopic surgery can be used to cut the tight ligaments and remove the scar tissue from the shoulder. Some surgeons may use repeated pain blocks after surgery so the patient can participate in physical therapy after surgery.
