I have ibs symptoms, however all of my blood tests and x-rays have came back normal. do i even have ibs? what should my next step be?

IBS Dx & Tx : Ibs is not defined by blood tests, imaging or other diagnostic tests & most don't need any of these tests. Depending on the specific symptoms, abdominal imaging, endoscopy & stool studies may be needed, not to diagnose ibs, but to rule out other possibilities. Start by educating yourself about ibs, stress reduction & dietary modification http://www.Aboutibs.Org/site/about-ibs/management/ibs-diet.
