Due to sedentary work at the computer, my back often began to hurt. After searching in Google for solving this problem, I came across a description of a massager - an inversion table https://homus.org/best-inversion-table/
At first I thought that what this massager can help with, it looks unattractive. But after reading reviews about it from customers, I decided to order myself. After several applications, the back became much less troubling.
