Get enough rest, even if it involves taking a sleep aid - it's temporary and
helps in dealing with the pain and
anxiety that results.
Keep moving to the best of your ability - gentle walks and/or yoga to stretch out. Swim in warm pools if that's an option - less pounding on the joints. Whatever you're comfortable with - but keep moving......
Keep doing things you love on a creative level - paint, write, sculpt, play an instrument - where ever you passions lie - nurture them.
