Hi, I went a ksharasutra on last Saturday for fistula which has no external opening and also for pile mass. Today I went again to hospital for consultation. Doctor said after 5 days also no improvement in healing and prescribed one powder to use for sitz bath. I am worry about no improvement in healing. Anything needs to worry or it's normal? And I am on fully liquid diet due to empty stomach, gas is forming in stomach which is irritating a lot. Any solution for this? Please reply. Thanks in advance.
