Bloody Hell...

Came home today from being readmitted to the hospital via the ER and curious if these issues have happened to many on this Forum. I had uncontrollable bloody/watery leaking from my drain which was eventually stopped by meds after ensuring the surgery stapling hadn't been compromised. Then, a short time after being readmitted, I had watery, bloody stools- and I don't mean a little bloody- A Lot! Surgeon on staff with my Surgeon said it was blood pooled in the intestines and would stop in a day or two. The Nurses said they'd not seen so much coming out of a drain before but my hemoglobin count is fine. Anyone with a similar situation and if so, what was the explanation given? Thanks!
