The right dose initially should have gotten rid of the pain. Maybe they need to check your Sed Rate and CRP. I know how painful that is, and in the beginning it wasn't showing up in my blood tests. As soon as I started the Prednisone it took 2 days to feel relief. I am a healthy eater. No meat or poultry in years, and balanced diet of fruit, nuts, spices, fiber, plant based proteins etc. It still got me. One thing I did incorporate in my diet was 3 to 5 prunes a day. My husband, physician, sent me links about them being a good anti-inflammatory. I posted somewhere in this forum. All I know is I am down to 2 mg, after almost 3 years. Hopefully, will go down another 1/2 at this end of this month. Very little pain in one shoulder and hand. I can live with it as long as my blood tests are normal on Tuesday. Feel better and make sure you get a second opinion with Rheumatologist.
