Hello Mike,
i was sorry to read of your mis hap which can happen to any of us, and its seems its easily done,
how ever i hope the pain and bruising will gradually subside and that your operation will give you a new lease of life.
my wife a few years ago tripped up on a paving stone in the high street and ended up in hospital having fractured her arm above the elbow
spending a few weeks in the hospital,
then a few months later she caught her night gown on the bedroom door handle and fell down hitting the other arm again another trip to the hospital x-rayed but nothing showed how ever she thinks the hospital hadn't carried the x-ray properly as she feels a twitch at times when the bones move in her shoulder,
but it shows that even myself iv tripped as i think its because im either not looking where i walk or simply for not lifting my feet , iv noticed people of a similar age walking around a super market , sort of dragging their feet,
sadly these are the problems as we age and that's including myself
