those tests would come out normal with IBS. basically, IBS is the diagnosis when they ruleout everything else. Which is sometimes it's a catch-all.here's a few ideas - keep a food diary to see if you can identify which food trigger problems. I've heard the books Carol and Amy mentioned are really good. Also, you might want to keep a diary of other things to see if there re non-food related triggers. I know for me, stress is a biggie! Also just eating poorly - weird times, high fat - can do it too for me.I'm not sure what your symptoms are other than pain. I don't have personal advice for treating that since I only get pain associated with either D or C - not just in general (and people who do get my complete sympathy). But if you are dealing with D, look into calcium (see OTC forum). A lot of people have success with that and as a woman, it's usually something you need a lot of anyway (I know my doc was really happy I was taking it). If it's C, look into magnesium. Another thing people have had success with. If you alternate like me, try a combo - 2:1 calcium:magnesium ratio seems best for me. Fiber can also help with both. Peppermint is a natural anti-spasmodic although if you have acid reflux, it's a bad idea as it will aggrevate it.these are just a couple of ideas. In my book, they're relatively simple things you can try over the counter. A doctor can help with more. Also one other thing to look into is hypnotherapy or cognitive behavioural therapy (see the forum in the coping tools section). A lot of people have success with pain management that way. I've done hypno and found it helped tremendously.take carenancy
