Oh my goodness, I'm so sorry this happened to you!
Are you still in the hospital? Has the surgeon explained why you're having so much fluid build up? Please tell the doctors and nurses that you can't breathe. They could always do a few rounds of dialysis to get the excess fluid out of your system. They did that for my dad after he had heart surgery and a lot of post surgery edema (fluid build up).
You're in my thoughts and prayers. (((hugs)))
Dx'd Crohn's in '99 at 28. Proctocolectomy and ileostomy in '06.
Disease-free, medicine-free, and very thankful to be healthy again.
