It becomes a depressing cycle, you stop getting involved and "accept" so we stay home and start reducing our exposure at first gradually and then we seem to be home all the time and its an effort just to go to the letter box.
There is a real danger here which I discovered when I got better and started walking a good distance again and that is atrophy. It really sneaks up on you.
Its taken me 2 full months of climbing stairs again (we use an elevated train here) to be able to walk without holding the rail.
The trick is to push hard through the pain barrier so your muscles dont become 'untrained". It really is a matter of use it or lose it, easier said than done though
