They have yet to send me to one. This is just my PC. I am wondering if i should follow up with a pulmonologist

Thank you for your response @penthewen! The pulmonologist appointment was on May 19 and the office called and rescheduled it to the middle of July. It is very frustrating! He wanted to rule out issues with my history of asthma (that has been controlled for over two decades) and he also wanted to rule out in a cardiac issues. I actually had an echocardiogram when I was in the intensive care unit for the system failures. My ejection fraction was in the high 60% range and it had only been a few months. I had the echocardiogram he wanted me to get which is basically identical to the one I had when I was out of state and in the intensive care unit I also had pulmonary function test, which showed that I had no obstructive airway issues, but did mention something about my oxygen perfusion? And, of course, I had the repeated CAT scan, so I will not know until the middle of July what he thinks about the test results and everything that is going on. I just know that I have been extremely short of breath since that experience last year, and nobody can put their finger on it. This long Covid stuff really has me wondering because I have so many of the problems that most folks do with this DX. I would really like to at least get back to walking my dogs! I know it will take time as I cannot walk to the mailbox without sitting on the ground to get my breath.
