Psoriatic arthritis (PsA) flare-ups can be triggered by a number of factors, including:

1. Stress: Physical or emotional stress can trigger a flare-up of PsA.
   
2. Infections: A bacterial or viral infection can trigger a flare of PsA.
   
3. Physical activity: Overuse of joints, or sudden, intense physical activity can trigger a flare of PsA.
   
4. Weather: Changes in temperature and humidity can affect the joints and trigger a flare of PsA.
   
5. Injury: An injury to a joint, such as a sprained ankle, can trigger a flare of PsA.
   
6. Medications: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids, can trigger a flare of PsA.
   
7. Dietary triggers: Some people with PsA may experience flares in response to certain foods, such as gluten or dairy.
   
8. Hormonal changes: Hormonal changes, such as those that occur during menstruation or pregnancy, can trigger a flare of PsA.
   

It's important to keep a journal of your symptoms and triggers to help you identify patterns and avoid triggers that may worsen your symptoms.
