Hello Ray and welcome to HealingWell,
I am sorry to read of your rough time and failed attempts at weaning off of Prednisone. Pericarditis may cause pleuritic pain as well as an elevated Sed Rate.
I have read if you have been on Prednisone long term you should only decrease the dose by 2.5 mg per week. Perhaps you have been trying to wean to fast. Just a thought and I am not a Doctor so please do check with your Dr. re this slow wean.
Keep hope and know that things will turn for you.
Kindly,
Kitt
