Hi Doctor, My Father Is 63 Years Old And Is

Hi Doctor, my father is 63 years old and is a know patient of Hypertension and Sugar. Has had PCTA stenting done in 2006. Now this is the second episode of this event - stomach pain on left side with vomiting and diarrhea. this lasts for about 4 days - and goes way. DUring the 1st such episode we did all the possible test and everything was normal - no kidney stone, no gall bladder stone, ecg also normal. He is also a know patient of regular smoking and alcohol very very rare. We suspect that spicy diet might be the reason- please provide your inputs.
