What is the pain in the asshole?

If the anus is particularly painful, it is mainly caused by some anorectal diseases. At this time, you should be vigilant and go to the hospital for examination in time. For example, anal fissure may cause such phenomenon, and it often occurs when the patient is defecating, because it is easy to cause dry stool, which will aggravate the symptoms of anal fissure. In addition, anal sinusitis, perianal abscess, internal hemorrhoids, external hemorrhoids, etc. may cause such symptoms. In addition, you should also be alert to the causes of tumors such as rectal cancer.

What is the pain in the asshole?

1. Anal fissure

The pain caused is cyclical and often occurs during or after defecation. It is mainly caused by irritation from feces and expansion of the ulcer fissure. The pain is paroxysmal burning or knife-like pain and can last for several minutes; the pain subsides after the stool passes. In addition, due to the stimulation of defecation, the internal sphincter may be in continuous spasm, causing severe and persistent pain in the ulcer fissure; it can often last for several hours, and the patient is restless and in great pain; in severe cases, the pain can last for more than 24 hours. In addition to pain, anal fissures are often accompanied by symptoms such as bleeding and constipation.

2. Anal sinusitis

Generally, there is slight pain and heaviness in the anus. During defecation, the stool presses on the inflamed anal sinus, causing burning pain in the anus. If the sphincter contracts due to stimulation, the pain will intensify and radiate to the buttocks and posterior thigh. It is often accompanied by a small amount of purulent or mucous secretion with a foul odor, which may cause moisture, itching and other discomforts around the anus over time.

3. Thrombosed external hemorrhoids

In mild cases, there is a foreign body sensation, often accompanied by bloating and pain. Due to damage to the perianal veins, blood clots form thrombi, and purple round hard nodules appear under the outer skin of the anus, usually at 3 o'clock and 9 o'clock in the lithotomy position.

4. Perianal abscess

The main symptom is distension and pain, and when pus forms, the pain is like a chicken pecking at the skin. Due to different factors such as the location of perianal abscess, size of abscess, pathogenic bacteria and patient's body resistance, the symptoms and signs that appear are also different. Common ones include subcutaneous abscess around the anus, ischiorectal abscess, pelvic rectal abscess, retrorectal abscess, and tuberculous abscess. Doctors at Quanzhou Boshi Anorectal Hospital pointed out that except for the different main symptoms, these abscesses generally have fever, chills, constipation, and difficulty urinating. Unlike other parts of the body, more than 90% of perianal abscesses can form anal fistulas, which have a longer course of disease.

5. Internal hemorrhoids

The main symptoms are distension and burning pain, which is mostly caused by varicose veins, damaged blood vessels and thrombosis, which result in restricted tissue circulation and prolapse of the anus and cannot be retracted. It is common in stage II and III internal hemorrhoids. Therefore, it is necessary to reduce or surgically treat the tumor as soon as possible, otherwise the surface mucosa will easily bleed, be damaged, or even become infected.

6. External hemorrhoid edema

The main symptoms are distension and burning pain, manifested as a localized lump at the edge of the anus, which is hard, smooth, shiny and obviously tender. It is mostly caused by fatigue, straining during defecation, or surgical stimulation.

7. Rectal cancer

There is no pain in the early stage, but later as the lump grows and ruptures, the anus may feel heavy and painful. Common symptoms include changes in bowel habits, bloody stools, abdominal distension, abdominal pain, and weight loss.

8. Anal foreign body injury

Most of them are caused by foreign objects left in the body due to trauma or improper diet, fish bones or bone fragments stuck in the anal canal or rectum. Therefore, you need to ask a doctor to check carefully and remove the foreign objects, and the pain will be relieved. If the retention time is too long, it may cause local infection.
