@desertsooner, I'm assuming you are taking the 40 mg prednisone in the morning. Some members have split their dosage between morning and evening to get them through the night with lower pain. It may be worth discussing with your doctor if your pain is better during the day but then gets worse overnight. I did find an older article that discusses the difficulty in diagnosing PMR that you might find helpful.
