Hey guys, I'm from Hyderabad India, I went in for Kshara Sutra treatment for Pilonidal sinus in Dec 2011. It cost a total of INR 15000 (USD 300). The doctor told me to sit in a luke warm water tub every day for 15 mins in addition to the kshara sutra treatment. I did all of this and I am completely cured. I found out about Kshara sutra through this website and I'm grateful to all the people that helped me out and to the founder of this website for providing this avenue. I'll be happy to answer any questions concerning this.
