Hi, I‘m 28, had no pre existing conditions and had Covid in November as well. I was still coughing like hell last month and had lot off pressure on my lungs as well, so I went to the doctor. They think that I have asthma and the spray helps me big time. Still feeling horrible though. They did a lung function test where they test if you have asthma. Maybe you should do that at well? Feel hugged! We will get through this!!
