I hurt from terrible pains in lower abdomaine probably intestins! I have had similar thing before but nothing to this degree and had a barium swallow done, nothing showed and low and behold it went away and I thought nothing about it. By the way IBS was mentioned but nothing followed through any further as it went away. A week ago I got what I think is the flu and was throwing up and had a bit of diareaha. Now I have a terrible ache lower abdomaine and then on and off I get these terrible cramping pain. It hurts so much, sometimes I am unable to get to the bathroom and so I just breath through it, almost like labour breathing and evencually the pain will subside. Stuck with the ache all the time though. When I can make it to the bathroom sometimes all that happens is passing wind and that does make it feel a bit better. Other time I just want to have a BM but nothing comes out and I just pass wind. It's very uncomfortabld and hurts a lot. Other times I might actually BM but it's hard too, I have to really push!
What I have read up and it states that it's to do with foods you eat IBM. I have noticed if I eat yogurt I can have terrible cramps, also spagetti sauce. Other than that I don't know if it's to do with food or what. I know I have to keep a diary of what I eat and how I feel after eating it and later on. It's so confusing though. I eat a lot of whole grains and whole wheat by the way.

Any thoughts or suggestions/help on what to do to get ready to go speak to my doctor about this. I hate the pain. I know what foods cause problems vary from person to person so it's hard to ask what I should avoid! I am so frustrated with this all and I hurt a lot. This week if I go to the doctors all I can see is a walk in doctor, my doctor is away this month!
Please help me out, thanks!
