Back home again. Things turned out a bit more complicated than I had thought.
Short and sweet: I have a pouchitis. This means that the pouch is inflamed. This explains why I didn'T feel too well recentlly. But I still felt 1000 times better than with the UC.
Pouchitis had to be treated with an anitbiotic IV (Metronidazol) and local application of cortison (go figure what that means

).
Might have been the first and only time I got a pouchitis. It only becomes chronic in about 3-5% of the cases.
Cause? - Completelly unknown as usual.
LEt'S see what the future brings...
Might have lost some pounds due to the loss of appetite from the antbiotics and the "glorious" hospital food.
Trainingwise it is back to buisness next week.
@feature boy: Thx. I was surprised myself about how easy those reps were.
