Here's the first installment of Paul Ingraham's re-evaluation. I've been waiting for this! My experience has been much like Paul's -- the "trigger point" has been the clinical concept that's served me best, in dealing with pain, but -- it doesn't really hold water. There are also many times when, mysteriously and frustratingly, it doesn't work at all. And the theory behind it doesn't entirely make sense.
One big plus to leaving it behind would be leaving behind that ridiculous name. I've always hated the term "trigger point." I much prefer the older, native English, and more frankly ridiculous "knot."
