Talk to Gynecologist on Pilonidal Sinus

Dear Dr.

I have got a small hole in my back out of which sometimes puss and blood comes out, I have been taking antibiotics and it's been greatly improved however still sometimes when i try to clean the area it seems sweaty, so I want to ask is there a non surgical treatment for this problem? Or do you laser treatment for this problem? I am very scared from surgery even though my sister had been operated by you with a very successful review but still I want to know if you can do laser treatment for this thing or you can suggest me If this can be cured without surgery
