I'm confused. I have many of the symptoms associated with ibs; painful spasms in my abdomen, occassional bloating and burping a lot with a bad taste in my mouth. I also often get a strong buring sensation just below my breast bone. I tend to get quite stressed out, and thats probably what started this, though even when I'm perfectly calm and unstressed it doesn't go away.However I don't have any constipation or diarrhea, which, according to everything I have read are some of the main signs of ibs. My doctors are convinced that I have ibs although I have not undergone any tests to check if there may be any other cause.Can ibs be diagnosed with out doing tests? especially if my going to the toilet seems to be just as normal? Please help - I want to find out what is wrong with me and if I need some specific treatment. I have been taking peppermint oil capsules and these may be helping a bit,but the pain isn't going away. whats wrong with me?
