I have been getting an awful pain in my upper chest and upper back, it hurts to take a deep breath, and nausea. It happens about once a month for about 4 days, 3 to 5 hours each time. I have seen doctors for other problems and they don’t listen and blow me off. I don’t want to waste my time looking for one to help me, so if anyone knows about this please help. The more info I have the better I can communicate with a doctor. Thank you
