If its not paining or bothering you, you dont need a surgery at all, a surgery is needed when its very necessary. I suggest that you just take care of yourself. doing a simple research on google will tell you what to do. and you will be fine for years except if you mess with it by not eating right or etc.. it would get worst and worst, painful and u will be need a surgery.
And no, it will never fully go away. it might get smaller, better, but it wont fully go away without a surgery.
Goodluck.
