Psoriatic arthritis can affect both small and large joints and cause great tiredness. Try these steps to ease symptoms:

Move often. Take a one-minute break every 20 to 30 minutes. Go for a short walk, stretch or just move to ease stiffness. Set alarms to remind you.
Wear clothes that feel good. Choose fibers such as silk or cotton that are easy on the skin. Don't wear clothes that feel tight or rub the skin.
Choose roomy shoes. Skip tight shoes, high heels and footwear with a narrow toe box. Opt for shoes that don't pinch your feet, even if they're swollen.
Reduce stress. Work can cause a lot of stress, which can make psoriatic arthritis symptoms worse. Ask for help when you need it. Take time to relax or meditate daily.
Make healthy lifestyle choices. A healthy lifestyle can help you feel your best, in general. Try to keep a healthy body weight, exercise regularly and stick to a regular sleep schedule.
Change your schedule. Ask your boss about working from home sometimes. Or ask if you can work more on the days you feel well and less on the days that your psoriatic arthritis symptoms flare. Save up paid time off for days when you really need it.
