I am NOT on TRT and you are describing exactly what I have, literally using the same words I describe it - it's uncanny, I thought I wrote the thread title! That doesn't guarantee it's the same thing though.
I have been having that "asthma" issue since 2018. It's not 'triggered' by anything - it starts the moment I get up in the morning with varying intensity during the day and during the week. In my case TRT is not the issue since I am not on it - I have a low normal free T with a high SHBG. I also have sinus /back of head pressures and headaches everyday, starting at noon, and fatigue when these are very pronounced. Sometimes these lead to getting a cold sore so I suspect a viral reactivation (like HSV1), or weirdly weak immune system (autoimmunity or cancer).
I am doing a CT scan of the chest next week - the chest xrays didn't show anything. The autoimmunity blood tests did not show any elevated inflammatory markers.
In my case, I can get deeper more satisfying breaths with a mild beta agonist - I use 100mg p-synephrine, since I don't have a prescription for "asthma".
