What is causing my flank pain & constipation?

[jgenna72]

I need some help please. I suffer from severe constipation, sometimes I can go for two to three weeks with a single movement. When it lasts that long I can barely eat, if I do eat an actually whole meal then within minutes I feel the urge to vomit and I have no control over keeping the food down. Also when I feel the urge to go to the bathroom, when I try and push at all I have intense pain across my lower abdomen like pressure on my uterus and I can even feel my ovaries and the pain is so overwhelming. Sometimes I even get light headed from the pain... I have tried many things, laxatives, enemas, colon health daily tablets, yogurts, increasing water... and yet that can help, but only for that one day.. then starting the very next day the constipation starts all over again. I also have flank pain on my left side that runs from my low back around the front of my side to below my left ribs.
I do take pain meds for back problems so I know that those can contribute to constipation and was recently diagnosed with MS back in 2010, but I am not sure I can just write off my constipation and pain due to those two issues.

Can someone relate or help guide me in the right direction... I am not sure what direction to take, and I just feel sick and unhealthy when I cant go to the bathroom.

Thank you in advance for any assistance you can offer!!
