Came To Indy To Attend The Indy 500 And A

Came to Indy to attend the Indy 500 and a relative, 64/w/m ate spicey shrimp for an appetizer and lasagna for the entree and within an hour or so started to get shakey,diarrhea,weak,back hurting and feeling bad. That was 28-30 hours ago and he still doesn't feel good, maybe a little bit. Had some Gatorade and chicken noodle soup tonite. Food poisoning or something else?
