I am suffering from stomach pain since one and half year.I have done every test like colonoscopy, endoscopy, barium test, Blood, stool test, Cat scan and doctor couldn't find anything wrong with my Intestine and stomach.i got this problem suddenly and still suffering. The symptoms include severe stomach pain, constipation, diarreoa,severe chest pain, back pain etc. recently, Doctor told me that It can be IBS. So, does anyone with IBS experience similar problem and How you coping with this.
