Last one hit me as I was driving to a dental appointment in Dallas. My left arm started hurting and I began to sweat profusely. Thought for sure I was having a heart attack or stroke when I started getting a "pulling" pain in my groin area. Pulled over in a Hobby Lobby parking lot and threw up. Headed straight to the Emergency Room and I threw up about 15 times when I was laying on the table. Didn't stop until they shot me up with a pain killer. Worst pain I've ever had.
