As soon as I entered the door, I told Dr. Mars the cause of the disease (low back). Dr. Li told me that it would cost 200 yuan for ten courses, so I don't need to check. After I tied it the first time, it didn't work. At Dr. Li's repeated request, I had to make an appointment for three courses of treatment (adding a special needle for 100 yuan, which looks like an old needle to me). Generally speaking, there is no technical problem, but the position of the needle is wrong. If you can treat low back pain from another meridian, why not enter the needle from the standard? There are only two cases: 1 dare not prick, 2 standard needles are faster, and needles in other places are charged several times more.
