Causes of waking up at night due to aching pain inside the anus

Generally, waking up at night due to a painful sensation of heaviness or pressure inside the anus may be caused by factors such as improper diet, hemorrhoids, perianal abscess, proctitis, or ulcerative colitis. 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. Improper diet: Consuming excessive spicy or irritating foods during dinner—such as hot pot or spicy hot pot dishes—may irritate the gastrointestinal tract and lead to anal discomfort or pain. It is advisable to choose light, easily digestible meals for dinner and avoid excessive alcohol consumption.

2. Hemorrhoids: A common anorectal condition, hemorrhoids may be associated with chronic constipation, diarrhea, prolonged sitting, and other factors. When hemorrhoids become inflamed, swollen, or incarcerated, they can cause a sensation of anal fullness or pain, sometimes accompanied by rectal bleeding or prolapse of hemorrhoidal tissue. Patients are advised to use medications such as Ma Ying Long Musk Hemorrhoid Ointment, Huaijiao Pills, or Huazhi Tablets as directed by a physician.

3. Perianal abscess: An acute infectious disease characterized by local redness, swelling, and pain around the anus, often accompanied by a feeling of heaviness or pressure. Abscess formation may result from infection of anal glands or secondary infection of pre-existing anorectal conditions such as hemorrhoids or anal fissures. Patients should follow medical advice in using medications such as Cefaclor Capsules, Jinhuan Ointment, or Compound Jingjie Lotion for washing.

4. Proctitis: This condition may be related to poor dietary habits or pathogenic infections. Inflammation can irritate the rectal mucosa, causing anal pain and pressure. Other symptoms may include increased frequency of bowel movements and rectal bleeding. Patients are advised to strictly follow medical instructions when using medications such as sulfasalazine enteric-coated tablets, acyclovir tablets, or doxycycline hydrochloride tablets to manage symptoms.

5. Ulcerative colitis: A chronic nonspecific inflammatory bowel disease potentially linked to genetic factors or weakened immune function. The condition primarily affects the rectum and colon, with symptoms including diarrhea, mucus-filled bloody stools, and anal discomfort or pain. Patients should receive treatment under a doctor's supervision using medications such as mesalazine enteric-coated tablets, olsalazine sodium capsules, or prednisone acetate tablets.

In daily life, it is recommended to maintain cleanliness of the anal area, avoid prolonged sitting, eat a light and easily digestible diet, avoid spicy and irritating foods (such as Sichuan pepper or skewered spicy food), and develop healthy bowel habits to help alleviate discomfort.
