A long strip in the anus that is harder to the touch may be caused by internal hemorrhoids, anal papilloma, anal fistula and other causes. 1. Internal hemorrhoids: Internal hemorrhoids are varicose vein masses that occur above the anal dentate line. When internal hemorrhoids occur, symptoms such as blood in the stool, prolapsed hemorrhoids, and constipation can occur. At the same time, it can also lead to the emergence of a hard and long strip felt inside the anus. 2. Anal papilloma: When the normal anal papilla is stimulated by inflammation for a long time, it can make fiber proliferation and promote the formation of anal papilloma. Its surface is smooth, its texture is tough, and its shape is mallet-like. As a result, the situation of touching a hard strip inside the anus occurs. 3. Fistula: Fistula may also lead to the occurrence of a hard strip felt inside the anus. For example, when an abscess occurs around the anal canal or rectum, it can lead to the formation of an anal fistula. This causes a sudden burst of excruciating pain in the anus. Recurrent episodes of spontaneous perianal pus or swelling can also occur. When there is a long strip of hardness in the anus, it is recommended to pay attention to rest, avoid exertion, eat a light diet, avoid spicy and stimulating food, pay attention to local hygiene, so as not to aggravate the symptoms. At the same time, if the symptoms are serious, it is recommended to consult a doctor in time, under the guidance of the doctor to carry out targeted treatment, to avoid delaying the condition.
