Monday afternoon I ate a sandwich with bacon from Subway. I felt fine. I went home and at 11:00 o'clock the next day I was sick, dizzy and had upper back pain. I threw up a couple of time but that was it. Are these signs of food poison, heart attack or what? I am still dizzy feeling and my face and nose sometimes has a tingling sensation. I feel terrible and I thought it was vertigo. Never has it in my life. I am 56 years old. Thanks.
