Bowel Blockage Anyone?

Hi there, I went to the emergency room late Tuesday , 8 days out from surgery. I was vomiting, and had severe pain in my lower right abdomen.(if one more person told me, it was what i ate, i was gonna hurt somebody) I ended up having an Ielius, bowel blockage, where the bowel goes paralized. I was wondering if anyone else has had this. Is it a fluke? or a side effect from the surgery? Please advise. Thanks.
