--as I've been busy with SAT/ACT season and haven't been on here much, but I can only add my good hopes and wishes for your son's recovery.

Sadly, this is just the type of situation which highlights how bad it is that Braintalk has been down for so long; while we do have the Spinal forum here, it does not (yet) have the depth of database or variety of experts that could well be helpful . . .

Let's hope that time will be on his side in this.
