Now that Johnny is doing better, I can say how worried & stressed I've been. What caused the many falls that sent him to the ER? No one is sure. The eyedrops he was allergic to? Something that didn't show up on all the X-rays, CT scans, MRIs & in blood & physical tests he was subjected to for 3 weeks in the hospital & rehab? My money at the moment is on his haste, because now that he is finally(!) being careful, things have gone OK.
