I've been going to Spa West for about a year. Around December of 2005, I had my first Lava Rock massage. The girl performing the massage said, "it will probably be really hot, but if it's too too hot, let me know." Me, being the strong willed person I am, thought it was supposed to be as hot as it was. About a week later, I noticed red splotches on my chest. It was determined that I have/had Second Degree Burns from the rocks. Furthermore, it is almost a year since I had the treatment, and my skin is still red, dark, and the skin flakes off in layers. My skin is trying to grow back but is taking a very, very long time.
If you still do go to Spa West, DO NOT GET THE LAVA ROCK massage!!! You will be burned.
