I hope you're better now and have found some much needed rest. This post of yours was placed 9 hours ago, so I'm a bit worried because you didn't follow up on it.
I'm a bit late now to comment sensibly, but I think fledgling has made all the important points already anyway: go to the hospital if you feel such attention is needed. And as she said, a blockage within your intestines is a very serious matter, and if suspected it has to be taken care of immediately.
Well, the above is rather lame now, I suspect. I really hope you're doing better now. Please let us know how things are going. You've been obviously through hell, and that didn't leave us unaffected. It's just so frustrating to learn about a case like yours and feel so inadequate because I can't really be of help from afar.
