I was just diagnosed with gastroesophageal reflux disease last week and I'm dealing with this burning pain on the left side of my back around the breastbone and I'm also having shortness of breath. The doctor said it's GERD and I'm on medication, which is helping, but I'm still facing this breathing issue. Every 10 minutes or so, I feel like I need to take a deep breath or else there's this pressure and tightness in my chest. My blood tests came back normal with an HB of 13. Why do I feel like taking a deep breath every 10 minutes? Could you suggest any breathing exercises or regular exercises that might help with this?
