When someone tells me they have a persistent cough, my first questions usually have very little to do with the cough itself.
I'll want to know when it started, what was happening in your life around that time, whether it's worse at night or in the morning, whether company makes it better, whether you crave warm drinks or cold ones. I might ask about your sleep, your worries, the last loss you carried, the dreams you've been having.
This isn't because I think your cough is all in your head. It's because, in homeopathy, the cough is information — a single thread we follow back to the person it belongs to.
Two people can arrive with the same symptom and need entirely different remedies, because the symptom is shaped by the person carrying it: their temperament, their history, their particular sensitivities. A child who is clingy and tearful with a cold needs something different from a child who turns inward and wants to be left alone.
That's where we start. Not with what's wrong, but with who you are.
