I just finished yesterday taking Prednisone 20 mg and Zithromax( z-pak) for 5 days , for sinus infection. I was feeling better, but today I started having bad chills again( no fever), and it hurts to touch anywhere on my back, chest, neck, ribs, my skin actually hurts, and underneath my skin, i can t even wear a bra, also my ears are feeling very full and some pain with them, my sins uses are back the way they were before taking the meds, feeling very congested, I am just puzzled about this feeling of hurting everywhere else?
