I was driving and I started to feel shortness of breath and pain in my upper back. What could be the cause of these symptoms?
I recommend you see your physician about the pain. Pain in the back and shortness of breath can be a sign of heart trouble or problems with your lungs and they are worth investigating. As a general rule, any time you have a sudden onset of a symptom like this - particularly if it involves your breathing or pain in your chest - you should seek medical advice immediately.
