Ongoing constipation after anal fissure... I am unable to eliminate without chemical help. Used high concentration powdered magnesium but creates severe diarrhea which hurts in other ways. Have tried enemas (water and Fleet), mag citrate, softeners, fiber supplements ,senna... ANYTHING I eat goes down and gets stuck, leaving me unable to sleep or concentrate on anything, such discomfort I have become suicidal... so I don't eat much and have lost a significant amount of weight. .Colonoscopy 2 days ago shows nothing of consequence. X-rays show everything normal. Has been about 6 weeks now, Help please!
