I have been on 10mg prednisone, starting with 60 mg/day down to 20 mg/day for a month. At first I felt wonderful because my back was out and this took away the pain. However, now that I'm at the end of the regimen, I have started to experience the following: My entire mouth (lips, tongue, throat, inside of cheeks) feels almost numb--kind of like it's coated with wax. It's a VERY disturbing feeling. A few times I thought I was going to choke because it's also accompanied by extreme dry mouth. I am also developing a moon face, and have gained 5 pounds in the last 3 days. I am jittery and woozy feeling. I have finished taking it, and now I wonder how long it will be before I am "normal" again--or if there's anything I can take or do to help speed the recovery.
