Questions people ask
How many medical specialties are there?
Counting depends on the certifying body, but major boards recognize a few dozen primary specialties and well over a hundred subspecialties — the map organizes them so the count stops mattering.
Do I pick my own specialist?
Systems differ: some let you self-refer, many route through primary care. Either way, knowing which specialty owns your problem makes the conversation faster.
Is this medical advice?
No — it's an educational map of the profession, not professional advice. Whether you need a specialist, and which one, is a decision for you and your clinician.
