I can't answer your question, but I am convinced you should be able to get Lyrica in China through either an international hospital/clinic in your city or from the pharmaceutical company itself.  And, yes, you will probably need a prescription.

I took it for paresthesia of the feet (thanks to metal poisoning) some years back.

Write to Pfizer directly at www dot lyrica dot com.  They have an FAQ page.

Good luck!
