I'm fortunate to be as old as I am and only have a cranky hip. It doesn't hurt as much when I'm walking or moving around, but when I sit down to relax it reminds me who's the boss.
Yesterday I twisted my left ankle. Right hip, left ankle, it sounds like a conspiracy to put me in a wheelchair. The ankle bothered me most of the afternoon and evening, and I ended up taking a couple Aleve and going to bed very early. I tried to watch a movie but couldn't concentrate and ended up sleeping for almost 10 hours.
And my ankle still hurts, but not as badly as it did yesterday.
It's not like a sprain, it's more like the joint is out of whack. I feel like I might be able to pop it back into place if I knew how to manipulate it.
So. My advice to you youngsters out there is this:
DON'T GET OLD!
Of course I know one alternative would be to die young, and I don't want that either. A better option is to stay active, control your weight and keep moving. The older you get, the harder it will be to regain any measure of fitness you once had. Don't let it slip away as you move through your 30s and 40s.
In other words, don't spend the last third of your life trying to fix something that could have been handled when you were younger and the task was easier. It could happen to you.
