I went to a concert with a friend today. All day I felt perfectly fine. As soon as I collected my keys and hopped into the car I got extremely nauseous and had a severe stomach ache. It literally came out of nowhere. I had to pull over twice because I felt like I couldn't breathe and that I was going to vomit. My head was super dizzy and I just felt like someone beat the crap out of me. By the time I got to the concert I felt like my stomach was going to explode and I ran to the bathroom. I didn't have a BM but I just never stopped feeling weak then. We were standing up at the end of the concert and my legs were like jelly. These feelings have been happening a lot recently and it scares me. To make it worse I'm leaving for a two day trip tomorrow by myself and I'm trying not to get myself worked up but I'm horrified that this is going to happen during my 2+ hour car ride. Any suggestions??
