Psoriatic arthritis (PsA) is a chronic autoimmune condition that can cause joint pain and inflammation, often affecting people with psoriasis. Understanding when a flare-up is approaching can make a significant difference in managing symptoms and preventing long-term damage.
If you’re living with psoriatic arthritis, you might notice some subtle or obvious signs that your condition is flaring up. Early detection of these symptoms can help you take action, stay comfortable, and prevent further complications. Here are seven early signs that your psoriatic arthritis may be flaring up.
Joint Pain and Stiffness
One of the earliest and most common signs of a psoriatic arthritis flare-up is increased joint pain and stiffness. If you’ve been dealing with PsA for a while, you may already be familiar with this sensation, but flare-ups tend to bring about an intensification.
The pain may feel like a dull ache or sharp pain and can occur in any joint, though fingers, toes, knees, and wrists are most commonly affected. The stiffness typically worsens after inactivity, such as sleeping or sitting for long periods.
Why it happens: When PsA flares, inflammation increases in the joints, leading to pain and reduced mobility. This results from the body’s immune system mistakenly attacking its tissues, including the joints.
What you can do: During a flare, maintain gentle movement to avoid further stiffness. Some individuals find starting the day with a light stretching routine or a warm bath helpful. You can also talk to your doctor about modifying your treatment plan to include pain management strategies like anti-inflammatory medications, physical therapy, or topical treatments.

Increased Swelling
Swelling is a hallmark symptom of psoriatic arthritis flares. You might notice that certain joints, such as your fingers or knees, become visibly swollen, tight, or tender to the touch. The swelling may also feel warmer than usual and may even cause the joint to appear misshapen. It’s not uncommon for swelling to occur rapidly during a flare-up.
Why it happens: Swelling directly results from inflammation within the joint. When the immune system triggers inflammation, fluids, and white blood cells accumulate in the affected area, causing swelling and discomfort.
What you can do: To manage swelling, try elevating the affected joint and applying a cold compress to reduce the inflammation. Avoiding overusing the affected joint can also help, as this can worsen the swelling. If the swelling persists or becomes severe, consult your doctor about adjusting your treatment or exploring other options, like corticosteroid injections.
Fatigue and Low Energy
Fatigue is a less obvious but equally important symptom of psoriatic arthritis flare-ups. Many individuals with PsA report feeling overwhelmingly tired or having low energy levels during a flare. This fatigue is often more severe than the typical tiredness that comes with a busy lifestyle, and it may impact one’s ability to complete everyday tasks.
Why it happens: Chronic inflammation and disrupted sleep due to joint pain can lead to extreme tiredness. Additionally, the body’s immune system is overactive during a flare, draining energy reserves.
What you can do: While it’s important to rest during a flare, it’s also crucial to maintain a balance between rest and light activity. Try to pace yourself by breaking up tasks into smaller segments and taking breaks as needed. Talk to your doctor if fatigue becomes overwhelming, as they may adjust your treatment plan or suggest energy-boosting strategies.
Skin Changes (Psoriasis Patches)
If you have psoriasis and psoriatic arthritis, you may notice changes to your skin as a sign of an impending flare. Psoriasis patches, which appear as red, scaly areas of skin, can become more widespread, inflamed, or irritated during a flare-up. These patches can appear anywhere on your body, though they are most common on your elbows, knees, scalp, and lower back.
Why it happens: When the immune system attacks the skin, it causes cells to build up rapidly, resulting in psoriasis patches. These can flare up when PsA becomes more active, as the same immune response connects both conditions.
What you can do: Moisturizing regularly can help prevent dryness and irritation. Additionally, topical treatments prescribed by your doctor, such as corticosteroids or vitamin D analogs, can help keep psoriasis patches under control. Consult a dermatologist for additional guidance if your skin symptoms become more severe or troublesome.

Nail Changes (Pitting or Discoloration)
Psoriatic arthritis is often associated with nail changes, such as pitting (small indentations in the nails), discoloration, or thickening. These nail changes can be an early indicator of an upcoming flare. If your nails become brittle or discolored, it might be time to pay extra attention to your joints.
Why it happens: Nail changes result from the same immune response that affects the skin and joints. When PsA flares, the nails can become disrupted as the body’s immune system attacks the cells in the nail bed, causing them to lose their smooth, healthy appearance.
What you can do: Keeping your nails clean and trimmed can help minimize the risk of injury or infection. It’s also beneficial to avoid harsh chemicals that can worsen nail damage. If nail changes are becoming more severe, speak with your healthcare provider about appropriate treatments, such as oral or topical, to help manage your joints and nails.
Morning Stiffness
Morning stiffness is a classic symptom of psoriatic arthritis flares. If you wake up feeling exceptionally stiff, particularly in the joints, and find it hard to move freely, this could be a sign that your PsA is flaring. The stiffness often lasts longer than 30 minutes and can significantly impact your mobility early in the day.
Why it happens: The body is at rest during the night, and joints can stiffen due to a lack of movement. Inflammation from PsA further contributes to this stiffness, making it harder to get moving in the morning.
What you can do: Stretching gently and engaging in a warm-up routine when you wake up can help ease morning stiffness. Some people find that a warm shower or bath helps relax their joints. If morning stiffness is prolonged, your doctor may recommend changes to your treatment plan, such as adjusting medication or incorporating physical therapy to address stiffness.
Flu-like Symptoms Without a Fever
Feeling achy, cold, or nauseous without an actual fever is another sign that your immune system is responding to a flare-up. Many people with psoriatic arthritis report feeling “under the weather” during a flare despite not having any visible signs of infection. This can leave you feeling weak and unwell, which might be confused with flu symptoms.
Why it happens: The immune system works overtime during a flare, leading to general body aches, malaise, and other flu-like symptoms. Since PSA is an autoimmune disease, your immune system can attack healthy tissues, making you feel sick even without an infection.
What you can do: Keep track of these symptoms and note any changes. Rest and hydration are key to recovery, and taking over-the-counter pain relievers (if approved by your doctor) may help manage the aches. If flu-like symptoms persist or worsen, consult your healthcare provider for further guidance.
FAQs
Q1: How can I differentiate between a regular flare and a more serious health issue?
A: If your symptoms persist or become significantly worse or develop new symptoms like a fever, contact your healthcare provider immediately. Monitoring your symptoms and seeking medical advice to avoid complications is essential.
Q2: Can I still exercise during a flare-up?
A: Yes, gentle exercises such as walking or swimming can be helpful during a flare. However, avoid strenuous activities that could further strain inflamed joints. Always listen to your body and adjust exercise intensity based on your feelings.
Q3: Is there a way to prevent flare-ups of psoriatic arthritis?
A: While you may not be able to prevent flare-ups entirely, some strategies can help reduce their frequency. These include managing stress, maintaining a healthy diet, staying active, and adhering to your prescribed medication regimen.
Recognizing the early signs of a psoriatic arthritis flare-up can help you take steps to reduce its impact and maintain your quality of life. By staying proactive with your care and working closely with your healthcare provider, you can better manage your symptoms and minimize flare-ups.
