Is the effect of Baiyilai cold compress good? What effect does it have on cervical spine? Now my neck hurts when I play mobile phone at night. I want to buy some patches. Do you have any recommendations? I've used it, and the effect is ok. Summer blew a big bag of wealth around his neck. I feel dizzy every day, I have no spirit at work, and there is no good way. I saw it on the internet the other day and tried several stickers. The effect is quite good, and I can relieve a lot. As long as I pay attention to it and exercise more, I will get better slowly.
