I started having a pressure in my lungs about 5 or 6 weeks ago. It turned into a pretty good cough lasting about 3 weeks. I still have a little pressure and especially when deeply laughing I still cough and the feel the pressure. In truth I have had a cough to some degree for two years when deeply laughing as I got a cough two years ago which was totally gone and not a problem even at the gym but when deeply laughing it flares up almost as if the lung never got truly clear and now it is again. I went to the gym today and all OK except I still feel that slight difficulty breathing and pressure in lung. O2 tested @ 98% this morning (pulse ox) If I wanted to pay the copayment I would go see a doctor personally thank you
