You need to go see an endocrinologist to be checked out. Fasting, morning labs are in order, especially to check your cortisol level.
It's your adrenal glands (and cortisol) that tank when you are on Pred. Not adrenaline!
Pred can have long-lasting effects, on the muscles as well.
Are you having times of unusual sweating or fatigue?
Do they do a metabolic panel after Plasma? They should. The endocrinologist would do that as well. They need to check for albumin levels also.
Please find a good endo and be checked out!
