Drink made my back/neck ache?

So i used to go to Chilis pretty often last year , and the first time this happened it was with the monthly margarita the shark drink. i also got food. i noticed my neck and back started to really ache. i thought maybe it was from playing basketball or something. whatever.

we go back again at the end of the month for another one of those shark drinks , and get food. same thing. at this point im concerned as to why its occurring again.. we didnt go for a couple months, but one night me and my GF wanted to grab a drink. so we go again , its a new drink but its a monthly marg. and the same exact thing happens, this really arful feeling in my back and neck. and i know it had to be the drink because on the 3rd time its all i ordered.

For context , i had ordered monthly margs from chilis in the past with no issue , and ive had my fair share of mixed drinks / shots / etc from other food places/clubs/parties.

just curious if anyone has ever had the same thing happen to them ?
