Diarrhea and pain in the anus

Pain in the anus due to diarrhea is a very normal physiological phenomenon. The pain of diarrhea is mainly caused by obstruction of the anus and large intestine. The pain can also be caused by excessive pressure on the skin of the anal canal. Therefore, as long as the symptoms of diarrhea are treated, the anal pain can be relieved. There are many reasons for diarrhea and anus pain. You can read the contents of the article and correctly judge the occurrence of these reasons.

1. Anal fissure: This is the most common cause. When many people have diarrhea, their anus is irritated by feces, causing ulcers and fissures. The pain feels like a knife cut and may be accompanied by a burning sensation. It lasts for several minutes and comes in cycles. In addition to pain and burning sensation, patients may also experience bloody stools, constipation, etc., which is very painful.

2. Thrombosed external hemorrhoids: The patient feels a foreign object during defecation, which is caused by a blood clot. If the blood clot is large, it will also cause severe pain. Symptoms include damage to the blood vessels around the anus, and the appearance of purple, round, hard nodules under the anal skin.

3. Anal canal skin abrasion: The cause of this condition is rather special. For example, if the patient has inserted foreign objects into the anus or engaged in homosexual anal intercourse, the anal canal skin will be damaged, leading to severe pain during defecation.

4. Rectal cancer: Rectal cancer can cause diarrhea in the early stages, but there will be no anal pain at this time. In the middle stages of rectal cancer, when the tumor grows larger or even ruptures, symptoms such as dull pain in the anus, bloody and purulent stools will occur.

5. Perianal abscess: In the early stage of the disease, the anus only feels swollen and painful, but the pain increases dramatically after the abscess is formed. There are many types of perianal abscesses, such as rectal laryngeal abscesses and tuberculous abscesses. In addition to anal pain during defecation, there are also symptoms such as fever and chills.

6. External hemorrhoidal edema: Symptoms include the formation of smooth, hard lumps on the edge of the anus, and a feeling of heaviness and burning pain in the anus during bowel movements. Patients may suffer from this disease if they have undergone related surgery or have exerted too much force during bowel movements.

7. Anal foreign body injury: The cause of the disease is that the patient has swallowed fish bones or bone fragments, and the foreign body remains in the body, causing damage to the anal canal and rectum. If the foreign body stays in the body for too long, it may cause local infection.

There are many possible causes of diarrhea and anal pain. If the patient feels severe pain, it is recommended to go to the hospital for treatment.
