CBLM Holy Hospital provides an unmatched treatment with the best and advanced methods for curing anal fistula without any visible cuts and wounds. An anal fistula occurs when a small channel develops between the end of the bowel and the skin somewhere near the anus. Typically, anal fistulas can develop due to slow healing of infections, long-term inflammations, or when the glands in the anus are blocked and infected by bacteria, causing abscess that increases in size. Common symptoms of anal fistula include skin irritation and redness around the anus, constant and throbbing pain, smelly discharge from near the anus and rectal bleeding. There are a few uncommon symptoms as well, such as recurring fever and painful and uncontrollable bowel movements. If the symptoms persist, a doctor consultation might be necessary, who might suggest colonoscopy, or an MRI or CT scan to confirm diagnosis.
