I have had a terrible week with my crohns, with the big D throughout the day, nausea and stomach upset, light headedness and dizziness, and complete fatigue. I also have a painful lump on the inside of one of my bum cheeks and do not know what it is. I have been handling all that and then throughtout the night I started to get itchy hive like bumps all over my body. They are on my scalp, behind my ears, up my arms, all down my sides of my torso, on my behind, and now they are moving down my legs. As I said, they are very itchy and seem worse at night, but I may be imagining that. Also, my eyelids and above my eyes are swelled. I look terrrible. Has anyone had anything like this happen? I was on predisone, but have been off of it for a week now and I am on 4000mg of Pentasa a day. I assume it is crohns related, because I have felt so terrible lately, but I could use some insight.
