I'm so sorry this happened to you.
But, I'm glad you felt comfortable enough to vent your frustrations to us. Most of us have had accidents at one time or another, so you are in good company here. (((Big Hug)))
SueBear is one of our j-pouch experts, so hopefully she will be along soon to answer your question. From what I understand, this should not be happening over a year after surgery, but I may be wrong. I would let your surgeon know what's going on and also see if you can find some answers at www.j-pouch.org.
You will get through this, because you're a strong woman of faith.
And, I'll be praying that you find a quick resolution to this.
Dx'd Crohn's in '99 at age 28. Proctocolectomy and permanent ileostomy in '06.
Disease-free and medicine-free since surgery and very thankful to be healthy again.
