Been experiencing breathing problem mostly starts in the morning after I have my tea, get relief if I sit in air conditioned room. All tests normal including heart, x-ray, blood test. PFT shows obstructive breathing. My pulmonologist suggested seeing psychologist (as I also have anxiety history), but I know for sure it is not anxiety. Most of the times there is urge to cough out and clear the chest/throat and do produce sputum. what could this be.
