Went in yesterday because I felt like crap. I get married this Friday. They prescribed me Prednisone 10 mg *3 tablets daily * For 4 days, as well as an antibotic. My concern is A. ive never taken it before, and I'm not sure I want to start a few days before my wedding. can anyone give me some insight. Will I become puffy, weight gain. I literally cant have any of these things for my wedding day. Please let me know any advice you may have!
