###Human: Is surgery the only option to cure pilonidal sinus? ###Assistant: Hello. I have gone through the clinical images (attachment removed to protect patient identity). The reason why this occurs is elusive, although many hypothetical explanations are given. Surgery is the best and only curative option. The wound can be closed without any problems after surgery. Keeping the wound open is an outdated technique of operation. Generally, no scan is advised. You can get an MRI if you want to get it done but it will not be of great help. Do not worry. It is not a life-threatening condition. It will not spread to other parts of the body. It is an easily treatable condition. You should go and get it operated. I would advise you to reduce weight, and check blood sugars, and BP. For more information consult a general surgeon online -->
