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".

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
