I used to have right sided pain with IBS symptoms now It moved to my left side same symptoms, constipated then soft loose stools what can I do?

Confirm diagnosis... IBS can mimic many conditions, & vice versa. IBS is a diagnosis of exclusion, so an examination, a few simple tests, & assessment of symptom duration, intensity, location, quality, timing, etc. will clarify your course of action. Talk with your doctor please before self-diagnosing & self-treating.
