Sorry to hear about your problems, glad that you're back with us.
A little PT and you should get the use of your legs back.
Not to sound like one of those commercials, but it's true that falls ae the most common cause of injury among older people.
I read between 50-75 ambulance reports a week, plus I compile reports for client agencies. Both numerically and as a percentage of ambulance calls "Falls" are the largest call type for every agency.
"Falls" can range from a simple lift assist for someone who can't get out of their chair to something like or worse than Ancient_One experienced.
One thing that I tell people when speaking about fall prevention is that those little area rugs that older people seem to like are like land mines for the elderly. Slip on one of those and you could break a hip, crack your skull, or have some other sort of serious injury.
Be careful going up and down stairs as well.
