I can say that my pouch had some activity during my ileostomy days, but those "disappeared" at takedown time, try not to worry too much about it, it could means nothing big, perhaps your bottom was greatly inflamed during your UC days and now it is not fully healed, but in case the pouch is still healthy and you could use topical steroids (if something else doesn't work) to treat that area. Pyoderma disappeares, more or less, always, when the underlined disease is treated. So be positive eat as clean as possible, and perhaps let you prescribe some iron as I suspect you are anemic because of your fatigue. (I take a brand called tecnofer which is super, but don't know if it's available in your country).
