Psoriatic arthritis is an autoimmune disease, meaning it occurs when the body’s immune system mistakenly attacks healthy tissue, in this case the joints and skin. The faulty immune response causes inflammation that triggers joint pain, stiffness and swelling. Triggers include hormonal imbalance, smoking, drugs, infection and many others.
Treatment for psoriatic arthritis consists of twice daily moist heat or cold applications, exercises, and nonsteroidal anti-inflammatory drugs (NSAIDs). If there is little improvement or if there are permanent changes visible on an X-ray, then a disease-modifying antirheumatic drug (DMARD) or a biologic drug will be added to help prevent long-term joint damage. You cannot prevent this disease but can ease your symptoms and prevent long term damage by taking medication, exercising, minding your postures.
Change your position at work, at home, and throughout the day. Sit and stand up straight, and don't arch your back. Good posture helps you feel better. Take break in between your work, Put as little stress on them as possible. Use larger, stronger joints when you can, instead of smaller ones.
