Hi, for the last 2 years I had been having daily trouble breathing, chest pain, dizziness, and tightness in my chest. It gets worse on any little exersion (like walking to the mailbox) and my inhalers do not help. I am terrified as it feels like I'm dying and can't get a breath in. I have seen and still see several doctors and have done many tests. Primary care, pulmonologists, cardiologist, ENT, and gastro drs. More than 1 of each and nothing has helped yet. I am scared guys. Does anyone please have any experience with anything similar to this? I do have asthma, anxiety, and gerd. But no medicine for those has been helpful and my symptoms seem extreme for those diagnosis as well. I also changed my diet for gerd guidelines and avoid all asthma triggers. Please help with any advice.
