I've a frozen shoulder, for 6 months. i've been resting my arm but painful when i lay on it or use it. what can i do other than taking pain killers

See an orthopedist: Depending on the cause, frozen shoulder usually develops with decreased movement. Inactivity can cause the build up of adhesions that make it harder and more painful to move the shoulder. Either physical therapy or manipulation under anesthesia are alternative and more definitive treatment options. An orthopedist can evaluate the degree of impairment and make recommendations. Good luck.

Spencer Technique: There is a series of maneuvers that a doctor can do called a spencer technique that helps to break up some of the adhesions and other things involved in a frozen shoulder. These are generally not very painful and can be looked up online, but a doctor should be the one that does this technique on someone with a frozen shoulder. It can be dangerous for someone who is not trained to do this.

Physical therapy: Cortisone injection. Surgery. See a shoulder specialist! they will be able to get you better.
