I was put on Prednisone from the beginning of July to the beginning of September because of a bad flare up of my Crohn's Disease. Crohn's is basically inflammation in the intestines, in my case causing me to pour blood out of my ass. Anyways, this stuff gave me the most hideous acne/rash type thing all over my face, neck, shoulders, chest and back. After several trips to the dermatologist and months of treatment it's only half gone. Anyone had experience with this type of acne?
