well this has been an ongoing problem but its never went away. Well about 3 or 4 months ago i started having chest pain. At first i thought it was my upper chest , then i thought it was my heart , and eventually lungs. I got my breathing checked out and it was fine, i got my heart checked out. Keep in mind I've told them the various symptoms I've been having ( some pain in left arm, and upper back at times. I was even told i had an excellent heart. Although theyve said all this im still having slight pain here and there. I highly doubt its growing pains , particularly because im 20 so im not sure if im over reacting. Just hard to keep wondering and researching as to why im experiencing this. Any advice would be helpful!.
