If you have bowel movement but can’t pass it, you can give anal injection of cecropia, usually 20-40ml, or give 2 tablets of phenolphthalein orally, and most of them can achieve significant relief. If there is no relief, senna can be given. If this symptom occurs repeatedly and the effect is poor, colonoscopy should be improved.
