Ia-fog, your doc would need to know height, weight, age, medications. Family and personal history, and hand’s-on exam. Then perhaps a CBC, UA, thyroid function, and a liver panel. Maybe a chest X-ray too.
And of course there is the “eyeball” test — his, of you.
There’s a lot of info in those beginning tests and that’s truly the beginning. Or, maybe not.
Hope you feel better soon.
