Thank you for all your emails and sending the white light. It worked: Xavier seems fully recovered. He must have strained something working out. There is simply no other explanation. It’s completely gone now. Still mystifying… I owned an aerobics and strength training business for 17 years in Key West and never saw anything this extreme (and, honey, I hurt some people). My students called me Sergeant Sally. Haha… just made me meaner! But an extreme muscle strain is the only explanation left… he feels great now. Pura Vida!!!
