My Pcp Sent Me To Er For Severe Abdominal Pain.

My pcp sent me to er for severe abdominal pain. No fever but few chills off and on. Had X-ray in er and it showed a lot of stool in my abdomen. Was given IV for dehydration, plus, Toradol 30mg for pain & zofran 4mg for nausea. My pcp wanted them to do CT Scan of abdomen but the er practitioner said there was no need since all my lab work came back negative. For the past 10 days I have been on antibiotic macrobid for UTI. But nothing helped with the pain. When I was released from er they told me to. Follow up with my pcp but since it being the wk end I can't. I took two dulculax to help with the discomfort & had numerous bowel movements but to no avail with the pain. I feel like I am getting dehydrated again since I have a very dry mouth. I had increased my fluid (h2o) intake but have since slowed down due to the pressure & being so nauseated. What do you suggest. I'm in a lot of abdominal pain.....plz help until I can see my dr on Monday. Sorry I won't be able to get an answer as I am disabled & have no money to get your response. Thanks anyway.
