Hi- I hate to pass the buck here, but you really need to see a medical professional for this. While I am certainly no expert on IBS, it can really be a myriad of different symptoms, but it is a diagnosis of exclusion (or it was in my case anyway)- if you are having GI issues, you need to see your PCP, discuss your symptoms, and perhaps be referred for further testing. I am getting from your post that you are also having other symptoms as well. Try not to get too nervous yet- GI symptoms are very common and often require a workup for diagnosis. Good luck.
