I have been suffering from a nervous stomach my whole life, however about 6 months ago I started suffering from nausea, vomiting, and back pain on top of it. I went to the doctor, had some tests done and he diagnosed me with IBS. I cannot find any information that says IBS causes nausea and vomiting. My doctor prescribed me Amitriptyline. I asked him multiple times if this would stop the nausea, vomiting, and back pain and he said yes. However I got the feeling he was never really listening to my concerns and the symptoms I was describing. My first question is this: Does IBS cause nausea, vomiting, and back pain? And if so, will this medicine actually help?View Thread
