Review on Shiatsu Chair Massager Heat Vibration by Gelin Sepulveda

Cool looking pillow. At first the heat took some time to warm up but then everything was fine. Shitzu Balls work up and down the entire spine, or simply focus on the upper, middle, or lower back if you want to focus on one area. Vibration around the seat only. There is also a rotating movement for the back, which stretches the muscles over the long term, instead of a circular rotation. Unfortunately I had to return it as I had chronic lower back pain and used the HIGH function on my entire back. 3 times and caused back cramps for 10 days and I had to use muscle relaxants and painkillers as I couldn't stand up straight! For chronic back pain, we recommend definitely starting with the "LOW” function and just massaging for 15 minutes and then see how you do. I did the massage for 45 minutes, after which I immediately felt severe pain when I got up. It was just my personal reaction and it can't be due to anyone other than me and my own situation. If you turn the setting to HIGH, there will be a relatively deep movement of the spinal muscles, especially when you lean on it. I don't recommend leaning on a pillow as it increases the pressure. I recommend not doing what I have been doing for chronic pain. Start "low" and do it for just 15 minutes, then get up and walk around, take an hour break and see how you progress!
