From past few months when I eat any oily food then I get stomach ache (right side) and also I feel cramps in my stomach and some time I gets loose motion also. I could also feel that gas formation has increased these days. And I am also having hernia past 2.5 years but I was not facing any difficulty and as per doctors advise it was not necessary to operate it. But these days as I mentioned I am facing some problem after waking oily food, I could feel pain in my stomach and some toughness I can feel near hernia location. Please advice, I am worried.
