Doctors with different diagnosis

In December of 2020, I was diagnosed with Covid-19 and double lung pneumonia. Upon release from the hospital after 5 days in isolation, my release instructions were to use Oxygen 24/7 for the remainder of my life. The day I got back home from the hospital, I forced myself to exercise by walking every day and within 2 months I was walking 2.5 miles a day and was able to take myself off oxygen. I have not needed to use it since. (My resting Oxygen levels remain around 95 both day and night.)
Shortly after stopped the use of oxygen, I started having "Wet coughing" spells which typically were in the morning. Periodically I get them in the afternoon. I've tried using Albuterol to treat the condition without any success.
Because the coughing continued, about 3 years ago, I decided to contact a pomologist to see if they could determine what was the cause of the coughing. After the breathing test, I was diagnosed with COPD. (I had quit smoking some 32 years earlier.) The doctor decided to treat the COPD with 2 puffs of Spiriva Respimat each day.
After a couple more years, I noticed my COPD was not getting any worse and got to thinking that this is not typical of COPD because it is a condition that gets progressively worse as time goes by. I called a different pulmonologist to get another breathing test, trying to determine what exactly what is really causing the wet coughing. Upon completing the second breathing test, the doctor told me I didn't have COPD. I was advised that I have Age Of onset Asthma. So, now they are treating my Asthma with 2 puffs of Spiriva Respimat in the morning and 1 puff of Mometasone in the morning and 1 puff 12 hours later in the evening.
I still am struggling with prolonged wet coughing spells daily. They are also treating me for Ipratropium nasal spray for a diagnosed Rhinitis issue. Has anyone experienced anything like this? I really need help and don't know where to turn.
