I had a physical therapy in the beauty salon, called the ancient classic model, which was quite comfortable and made me feel comfortable all over. Has anyone done it? How's it going? Are there any side effects? Since last year, I've been applying one to remove moisture. I heard it's an old secret recipe of Chinese medicine. My shoulder used to hurt, but now it hurts many times. Much better. It's still very effective. There should be no side effects. Anyway, I have no adverse reactions. Chinese medicine should not have side effects like western medicine, I think!
