I'm 43, female with fibro (among many other dx). Having a terrible time with "digestive problems". I'll go a week with horrible constipation and then have bad stomach pains and cramps then forced(?) to stay on toilet for hours. I have been dx with IBS, and take prescription strength fiber for it. Don't think it helps. I constantly have stomach aches--never feel empty. My pain dr. thinks it is due to pain med,oxycontin. Anyone else suffer from this problem who takes oxycontin? Any suggestions? Sorry if this sounds too wierd!! please help!!
