Chickenbone, I recently had a similar experience with tooth pain. I suddenly felt tremendous pain in my jaw and decided to accept the pain and believe in my body's ability to heal itself. After a couple of weeks the pain disappeared. It was a good experience to just have the pain without too much mental tension and fear about it. I think there's a Buddha quote which I love (Levine mentions it also, these are my words, not a quote, because I didn't find it
When a person gets shot with an arrow, he right away shoots a second arrow at himself (fear, anger, panic about the first arrow). It's just that it is not necessary, being shot once with an arrow, to shoot ourselves again.
The somatic approach isn't new, just rediscovered. Wilhelm Reich from Austria successfully worked with it in the 1920s, after he split with Freud (he worked on patients that didn't respond to analyses, he pretty much did, what Levine does today, his patients also started shaking etc.). After that he tried to prove that there's a life energy in our body, which, once it's blocked, produces mental and physical illness. Bodypsychotherapy unblocks these blocks. In Asia it's called Qi-energy. Since there's no proof of it in western science, he was considered highly controversial. He also stated, that cancer comes from mental/energy blockages, that hurt the cells. He saw under a microscope, that red blood cells of a mentally healthy person (with little body tension/armour) looked much better than the ones of people with a lot of tension in the musles. He could diagnose their tension level just by looking at cells under the microscope. I think he was a genious. Of course in Asian culture none of this is new, since they believe in Qi, acupuncture etc. Reich called this energy Orgon energy.
Reichs work is fascinating and was groundbreaking in regard to body armour, somatic symptoms, energy blockages in the body that block well being and block the bodies ability to harmonize and heal itself. He usually worked with the patients tension in the muscles of the upper head/eyes first and worked himself downwards through the whole body, often amazing and powerful changes happened in the body and mind. He describes this in his book
