Does anyone know the operation of the small needle knife in the pain department of Foshan Armed Police Border Inspection Clinic? Is it expensive?

I don't think bragging is reliable, but the effect of small needle knife on some muscle inflammation is quite good and convenient. I played for 50 yuan. It's not expensive and it's not an operation. The doctor must find out. This kind of injection requires a lot of doctors, and if it is not well played, it will encounter blood vessels and nerves, which is very troublesome
