Sexually Transmitted Disease
Anal pain can occur with a number of sexually transmitted disease, including chlamydia, HPV and warts, gonorrhea, herpes, and syphilis. The pain may only be present when having a bowel movement, but it can occur separately too. In addition to the pain, patients might also notice anal discharge, minor anal bleeding ,and itching when they have an STD. Oral or topical antibiotics are the general course of treatment. If anal warts are present, they may need to be removed.
Anal cancer is not common, but when it does occur, patients may experience anal pain, bleeding, or itching. A growth or mass in the anal canal may also be present. This cancer is often linked to the human papillomavirus (HPV). In most cases, treatment involves a combination of radiation and chemotherapy. In the early stages, surgery might be able to remove small tumors. In late stages, an abdominoperineal resection might be considered if other treatments fail. This is an extensive surgery that removes the rectum, the anal canal, and part of the colon.
