Sunday afternoon I was at a restaurant and got very sick out of the blue. I ordered a bloody mary that contained a green olive, lemon slice and piece of celery. About 20 minutes after finishing it, I because very nauseous, it hurt if you touched anywhere on my stomach (pains I have never felt), sweating and soaking wet, dizzy, wanted to faint. That last for the whole day. That night and all of this week I have experienced lower back pains. I m not sure why I have the back pains. It is very low on my back, closer to my tailbone. what could this have been from and should I get it checked out? I dont have any of the other symptoms
