Hello Ganesh and welcome to HCM
Surgery is the choice of treatment for Hernia
. Their is no other way to get rid of it.
An hernia is sac formed by lining of abdominal cavity. The sac comes out from a hole in the fascia. For the treatment its needs removal of the sac and the weaker part or hole of he fascia covered by a mesh. So that reoccurance doesn't occur.
Your doctor advised you the right thing to go for surgery in a planned manner unless it is an emergency.
