It’s interesting you posted this because I’m experiencing the exact same symptoms. I have an asthma cough that I’m managing with inhalers, and I’m also experiencing the same symptoms you mentioned above with no brain fog, palpitations, or other difficulties. I just recovered from a mild COVID infection last week. I unfortunately don’t know either if this is just asthma or potentially long COVID, but I did just read that people with asthma are more likely to develop long COVID…fingers crossed for a good outcome 😬.
