Hello!
I'm new to this site and see that others over the past several years have posted having the same symptoms that I'm having, and I'm wondering if anyone figured out what this could be: for over 6 months I've had a persistent cough, occasional stuffy nose, tightness of chest and laboured breathing - although I can exercise without issue and sleep well. Some days are better than others but for the most it is a persistent feeling like an elephant is sitting on my chest. I've had normal blood work, clear ENT nose exam, clear chest X-ray and CT Scan. A round of antibiotics ruled out a bacterial infection, and GERD medication ruled out Acid Reflux. A neck ultrasound detected an enlarged lymph node above my left collarbone but so far cancer has been ruled out with these other tests. (I'm having a follow-up ultrasound in a month to see if the lymph node is growing.) I was told since all of my tests were normal/clear, the enlarged lymph node is my body reacting to some kind of infection but no one has been able to tell me what is infected. I've been to a respirologist who said I "may" have asthma and gave me Symbicort inhalers which I haven't started using yet as I'm not convinced it's asthma - I've also read that others posting on this site have not had success with Symbicort for these symptoms. If anyone reading this has had these mystery symptoms and has been diagnosed, and has had success with treatments, I would so appreciate learning about your experience.
Thank you!
