The feeling of sticking in the stool may be caused by dietary factors, anal fissure, constipation and other reasons. 1. Dietary factors: if you eat a lot of spicy and irritating food, the anus can be stimulated during bowel movements, resulting in a feeling of zapping. 2. Anal fissure: when defecating, due to fecal stimulation of the nerve endings of the trauma, can cause pins and needles pain after defecation. 3. Constipation: If prolonged constipation leads to dry stools, it can cause straining to defecate and may cause pins and needles in the anus during defecation. It is recommended that those who have a pins and needles sensation when pooping should go to the hospital to clarify the cause, and if treatment is needed, standardized treatment should be carried out under the guidance of the doctor to avoid delaying the condition.
