What causes pricking pain around the anus?

The main causes of perianal pruritus mainly include the following points: 1. Hemorrhoids: This is one of the most common causes, especially internal and external hemorrhoids, which may be accompanied by symptoms such as pain, itching, and bleeding. Hemorrhoids result from dilation of blood vessels or varicose veins near the anus and rectum. 2. Anal fissure: An anal fissure is a tear in the skin or mucous membrane around the anus, usually caused by passage of hard stool, with symptoms including severe pain and bleeding. 3. Bowel inflammation: Conditions such as proctitis or colitis may cause a pricking sensation around the anus and may be accompanied by gastrointestinal symptoms such as diarrhea, constipation, and abdominal pain. 4. Infection: Local infections around the anus, such as skin infections or abscesses, may also cause a pricking sensation. 5. Neuropathic pain: Certain types of neuropathic pain, such as sciatica or pelvic nerve pain, may radiate to the perianal area and cause a pricking sensation. 6. Other anorectal diseases: Conditions such as perianal abscess, anal fistula, and rectal prolapse (rectal mucosal prolapse) may also cause a pricking sensation around the anus. It is recommended to seek timely medical consultation to determine the exact cause and receive appropriate treatment.
