It is really useful. I often have this kind of trouble. Later, I tried ARPW's fasciotomy therapy, and once I felt very relaxed. I went there several times later, and now I feel my whole back relaxed. It has 448kHz+20kHz dual-frequency hyperthermia, and there are 33 electric correction modes. Is it a nursing instrument with very comprehensive functions? Thermoelectric therapy combined with fasciotomy nursing can make the body achieve good relief, promote blood circulation and help metabolism. I feel warm every time I finish it, and my back pain has really eased.
