I noticed some definite puffiness in my face and soreness in my breasts, as well as a bit of an acne outbreak on my face. My breast size actually increased a whole cup size...and I'm past the age at which you hit puberty. The puffiness in my face started a day AFTER I finished the prednisone. (I was on it to control poison ivy...I then had an allergic reaction to the topical medicine given to me and was put on prednisone again to counteract the allergic reaction. I had the 6 day dosage pack (4mg?) 3 times and finished the pack this past Sunday. The breast stuff occured after my 2nd pack. I'm assuming that may be the "fat redistribution" I've read about.... My stomach had a little bit of fat added to it...nothing major, however the weird thing is that my weight has been about the same. The thing I'm majorly stressing about is the "moon face" thing and I want to know how long this will last and/or what I can do to counteract it! Any help/information would be greatly appreciated.
