Since my last post, my son improved at a gradual rate to the point of being symptom-free. Regular massage therapy treatments from a woman also skilled in Chinese accu-pressure played a big role in alleviating his symptoms - he described it as like a fog lifting.

He recently skied for the first time in 7 weeks, reporting no symptoms (he's not allowed, by my order, to do jumps or non-groomed runs for this year).

All signs are we've turned the corner - for now, recognizing that this may be the beginning of dealing with these sorts of injuries on a regular basis. As a result, we're taking it very slow as he resumes activity.

Thanks to everybody, especially Mark in Idaho, for their most helpful support, ideas and reassurances.
