Suggest Treatment For Severe Shoulder Pain

I have constant pain throughout my body. both shoulders, especially the left. Both hips, especially on the right. Elbows, ankles. Many times I can t walk, or do so with pain. As I am doing dishes, I have to bend over the sink. More times than not, I have a hard time getting dressed and need help. I can only walk for a short period of time, then I have to sit down. At times my ankles seem to freeze . They also want to curl up, my hands and fingers do the same thing. I have been diagnosed with fibromyalgia, Osteoarthritis, and have had 2 back surgeries. I just can t handle the pain anymore. Please help.
