I'm experiencing some mild pain in my upper chest on both sides and also in my upper back, and sometimes even in the lower part of my chest. I went to the doctor yesterday, and he did an ECG, which came back normal. My oxygen level is 97, but I'm still feeling like I need to take a deep breath every 10 minutes or so, and Im not sure why. Could you help me figure out what's going on?
