I Am Questioning Food Poisoning From Red Wine? Had Dinner

I am questioning food poisoning from red wine? Had dinner last night with two glass of wine. Less than 1 1/2 hour later very bad stomach cramp and extreme diahhrea. Felt better after but stomach was still a bit sore.
Next day all is well. Tonight dinner and 1/2 glass wine (same one as night before) bad stomach pains, hot and cold chills. No diarrhea yet, but I know it's coming. I didn't think wine could be bad. Will it pass it the wine is off or should I be more concerned about what is off in the wine?
