What causes a sour, swollen sensation with a feeling of heaviness in the anus?

Under normal circumstances, a sour, swollen sensation in the anus accompanied by a feeling of heaviness may be caused by various factors such as prolonged sitting, poor bowel habits, proctitis, perianal abscess, hemorrhoids, and others. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Prolonged Sitting

Prolonged sitting can compress the pelvic floor muscles and blood vessels around the anus, impairing local blood circulation and causing tissue hypoxia, which leads to a sour, swollen sensation and a feeling of downward pressure in the anus. Regularly standing up and moving around, along with performing anal sphincter exercises (Kegel exercises), can help improve pelvic floor circulation.

2. Poor Bowel Habits

Constipation or excessive straining during defecation can cause over-tension of the muscles around the anus, resulting in a sour, swollen sensation and a feeling of heaviness. Improving dietary structure, increasing dietary fiber intake, drinking more water, promoting intestinal motility, and avoiding straining during bowel movements are recommended.

3. Proctitis

Proctitis is usually caused by bacterial or viral infections, which may lead to congestion and edema of the mucous membranes around the rectum, thereby causing a sour, swollen sensation and a feeling of downward pressure in the anus. Other symptoms may include diarrhea, mucus in the stool, or bloody stools. Under medical guidance, medications such as mesalamine enteric-coated tablets, norfloxacin capsules, or acyclovir tablets may be used to relieve symptoms.

4. Perianal Abscess

A perianal abscess is caused by bacterial infection. Inflammatory stimulation leads to pus accumulation in local tissues, which may irritate the anal nerves, causing swelling, soreness, and a sensation of heaviness. Symptoms may also include anal pain, redness, swelling, and fever. Treatment may involve taking medications as directed by a doctor, such as amoxicillin capsules, cefixime capsules, or ibuprofen sustained-release capsules.

5. Hemorrhoids

Hemorrhoids may be triggered by factors such as diet and bowel habits. When internal hemorrhoids are irritated or prolapse, they may cause a sour, swollen sensation and a feeling of heaviness in the anus. This is often accompanied by symptoms such as anal pain and bleeding. It is recommended to use medications such as Ma Yinglong Musk Hemorrhoid Ointment, compound algininate cream, or diosmin tablets under the guidance of a healthcare professional.

In daily life, it is important to develop healthy living habits, maintain a light diet, and avoid consuming spicy or irritating foods.
