It's good. They are doing electrotherapy. When I was chatting with my neighbors, they recommended me to go. Then they went to do their slimming and shaping projects several times. Obviously, they feel much better. The most obvious thing is that their fingernails are shining and their shoulders are sore. I felt a little insomnia before, but I slept well recently ... Personal experience, you can really try it if necessary. Amazingly, I am nearsighted, but every time I finish, my eyes feel super comfortable, as if they are much brighter. I heard from the physiotherapist that the acupoints of the human body have been calculated, so I will stick to it! !
