Safety questions worth asking ān quán · 值得问的安全问题

Before any treatment: Are needles single-use and disposed of properly? What is the practitioner's qualification and registration? What are the risks of this specific treatment for my specific situation? What medicines and supplements should I mention?

And the one that matters most: what would make you tell me to go see a doctor instead? A practitioner who has a clear answer to that is a practitioner worth keeping.
