Hello:Lately, one of the IBS symptoms I've lived with for years has worsened.I get this intense sensation of pain/pressure in my lower GI which descends to the rectal area.I feel this strong urgency to have a bowel movement, even though I may have had a recent BM. When this happens, it also causes urinary urgency. Makes it hard to sit sometimes.All too often, this rapidly generates upwards, and I experince quite intense headaches along with the lower GI tension.Actually, my entire body starts to feel tensed up when this "sensation of incomplete evacuation" gets bad. When it gets this bad, I can scarcely do anything without feeling exhaustedThis pattern is dramatically exacerbated if there is the slightest degree of sleep loss. In some sort of vicious cycle, this very pain makes it diffcult ot sleep.While a mild laxative brings temporary relief to this syndrome, it rapidly returns within a day.I haven't yet found a fiber source which helps this. Often, they seem to make things worse.Any suggestions?-Ira
