Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Yes, it can be fistula or it can be sinus. But it can only be known once the clinical examination done. I advice you to visit the near by surgeon which will guide you regarding the type of channel you have. I advice you to please take the surgery done because surgery is the only treatment option available. If the surgery is taken delayed, there is chance of infection. As the anal area is potentially dirty area there is chance of infection by the bacteria from the intestine. Please maintain the hygiene as it can prevent you from getting infec ion until you visit the nearby surgeon. You can do it with frequent washing and dressing with diluted dettol solution. I will be happy to answer your further concern on bit.ly/DrArun. Please hit thank you for me if you are helped. Thank you, Dr Arun Tank Infectious diseases specialist.
