How to differentiate a partial bowel blockage from an intense case of constipation. I struggle with constipation as i am on pain medicine after being hit by a car some years ago. It s nothing im unfamiliar with. However i have not pooped in the last 3 days. I am worried however for the following reasons a) about 2wks ago i developed a constant aching pain in my abdomen on the lower right quadrant btwn belly button and hip bone (I thought it may be appendicitis but dr ruled it out). I have PCOS and sometimes around my period a cyst will rupture, which was his guess. Well two days later my period started, the pain was gone. My period ended last week wed. b) for the last week my stomach has been making constant gurggling noises. Like air bubbles in my stomach juices. (Note i don t drink anything carbonated) c) i have been bloated but i was chalking that up to my period. d) i have not had the URGE to have a bm in the last 3 days but i have been farting regularly and daily. e) that pain referred to in bullet a came back saturday but is now gone unless i massage stomach. f) i took fiber pills, to no avail. So i took two duocalax on sunday morning. I got nauseous. However i took them first thing and on an empty stomach, so i dunno if that had anything to do with it. g) ive been using thst tummy massage to go poo (pushing and rubbing clockwise in lil circles). To no avail, except more tummy gurggling and farts. h) when i bare down as if to strain and pass a bm i feel nothing, usually ill feel it inside me....it will be uncomfortable. I don t have that feeling. Lastly and just add a sidebar- ive recently begun a severely limited, low carb diet. So ive been eatting a lot of protien, fruits & veggies, yogurt, keifer, cheese, eggs. Finally, about a year ago i had a paniculectomy, so it s very difficult for me to ascertain if im bloated, and if my stomach should feel so tight when i push and try to massage.
