Good luck and do keep us posted on what u do and how it all turns out...
BTW- there is a way to have a manual adjustment of the hernia via a well trained chiropractor....it is one way to see if u can have some relief....b4 u commit to surgery...and if it works u may not need surgery.
I feel u should try all means possible and surgery the last option...that is for me personally...diet and lifestyle modifications,....and if I can or need more, then I may try the chiropractor.....and if that still did not work, I would have surgery if I was in a place that nothing else worked...lucky for me, diet, and lifestyle changes with occasional meds do the trick for me....
Good luck and do let us know ur progress
