Last night around 10:30 i ate a bowl of caesar salad with the Renee's dressing and about an hour and a half later i got a terrible stomach ache and i felt like i would throw up... Im not sure what it is but it's not going away i couldn't sleep at all last night from the pain and pepto isnt working... what could this be? My temperature is 37.0 so i dont have a fever but my stomach hurts ALOT... any thoughts?
