Hi there. Thank you for posting your question with Healthcaremagic. I will do my best to help you.
The chances are that these "holes" will indeed heal over in the next few weeks. The problem is that pilonidal sinus
is very unpredictable. It is also a condition about which very little is known in therms of etiology or optimum treatment.
Here is the point though: Pilonidal cyst
tends to recur and erupt again and again like an ice geyser. If this is happening to you and the thing is interfering with the quality of your life, then go and have it dealt with surgically. The best operation for pilonidal sinus is still open wide wedge resection and allowing it to heal up by granulation. This is not for the faint-hearted.
I hope that I have answered your questions fully and been of some help. If you have anymore questions please contact me again anytime.
Dr Andrew Rynne.
