Sounds like you have been saved to tell us about this problem thanks to the quick thinking of your DIL and the diligence and expertise of the ambulance and hospital medicos. They say what doesn't kill us only makes us stronger.
Stay strong Tom 86, because the world is not finished with you yet. May you go from strength to strength as you recover. We want you to keep posting until the 12th of Never, and that's a long, long time.
