@obxpoppop Good morning -- As @dadcue just said , the best we can do is relate our experiences and there are many other conversations about who started at what dose and what was the tapering schedule and advice about splitting the dose and keeping a pain journal . @johnbishop may invite you to tell more about yourself.

There is likely a'miracle dose' of Prednisone that will rid you entirely of morning pain and stiffness in BOTH your hips and shoulders. For me that does was 30 mg after being on sub- optimal dose of 20mg. Because i am 66 yr old woman i was advised to take Ca++, Vit D (my bone density results show i only have osteopenia)
Before i went on Medical leave from my Molecular Biology position in biotechnology ( because i could not function with the persistent morning pain in shoulders) I drew this word problem on the white board ! ha ha. I did indeed keep a pain journal /heat map of both areas of my body recorded at three times a day !
the other figure shows what is going on at the cellular level and there are anti-IL6 recepetor biologicals approved for PMR - you may already have seen this web site ? : PMRandIL6.com
