Thanks. I had chest xray some years back. All ok. However I have a small lung nodule being monitored with annual CT scan. So far, not growing. So far have ruled out chest or lung issues, Asthma, GERD, deviated septum and numerous meds. Just comes and goes. Month on. Month off. Ramps up, peaks, then back down and ok for a month. Going on around 15 years now. One ENT doc said chronic sinusitis. Occasionally turns into sinus infection but only occasionally. Usually accompanied with post nasal drip. Tried sinus irrigation, various cough syrups, etc. nothing helps except to let it do its thing and wait to cycle back down. Very self conscious when coughing in public, in checkout at grocery store, etc.. I say “sorry, chronic cough. Not a cold or covid” You can tell by the look on their face “yea, sure”. 🥴
