I’ve heard prednisone described as a pharmaceutical sledgehammer. It definitely does its job but it leaves destruction in its wake. I’ve been on prednisone for chronic eosinophilic pneumonia for 10 months. Anytime I dip below 10 mg my lungs get super angry and I have to go back up. Every taper is a drama of crazy symptoms - I’ve had the excessive sweating but not the cold to follow it. Depending on the level of taper, my symptoms last from 1 -5 days. I’d give it another day and see if it gets better and if not check in with your Dr to make sure you are not relapsing on whatever the prednisone was fixing or your adrenal system is not picking up the slack from less prednisone. Hang in there - I know how you feel and it’s miserable but there is an end in sight!
