I have severe eosinophilic asthma. It took us two years to diagnose. I had to find a pulmonologist who is in private practice. Do you have a pulmonologist? At first when I showed up the doctor was not convinced I had asthma. All my testing was normal except a low lung volume which was not enough to prove asthma. We had to do the methacholine challenge test to prove it. Have you had that test? Also my asthma is triggered by allergies and my eosinophil count. but there are biologic injections that really help me. I get Fasenera injections every two months. There are several depending what asthma you have. Did they check your eosinophil count in your blood? I know they think you have asthma. so my journey is different but there are several different types not just a generic one.

Have you tried a nebulizer machine? It can help when your lungs feel really tight - it delivers the asthma medicine through a tube and it takes about ten minutes. It really helps me when my lungs are tight or I panic about my breathing. I have one I can use at home or take with me when I go out or travel. Some of the machines are large and heavy but you can also get a smaller portable one.

As far as COPD, it runs in my family and so does lung cancer and hat concerned me so I asked the doctor if he would test just to make sure since my uncle had COPD and he had to be on oxygen. They did a CT and tested specifically for COPD which there are specific tests and blood work they did. Have they done a CT or just an x-ray? I don't have COPD or lung cancer thankfully. but I am sharing all this to let you know to keep asking questions.

One other thing you could try is to check your oxygen levels when your lungs feel tight. You can buy an oxygen device at Walgreens or.a similar store. It is fairly cheap. It is called an oximeter maybe. You put it on your finger. It checks your pulse too. Sometimes oxygen levels only go low when your chest is tight. So even if they check it at your doctor's office unless your lungs are tight it might read normal. Just something else to consider. Hope they figure it out!
