Maybe your joints are inflamed and you wonder, could I have arthritis? And if so, what kind? Or you’ve been diagnosed and want to know how your condition is different from other types of arthritis.

Arthritis comes in many forms and may be inflammatory (where symptoms are caused by inflammation and can cause joint damage) or non-inflammatory (where symptoms tend to be caused by age or prior injury). Psoriatic arthritis (PsA) and rheumatoid arthritis (RA) are two of the most common types of inflammatory arthritis. They are similar in many ways, yet there are some specific differences that are important to understand if you’re living with either of these conditions.

Causes and Risk Factors of Psoriatic Arthritis and Rheumatoid Arthritis

Psoriatic and rheumatoid arthritis are both conditions that affect the joints of the body with episodes of painful inflammation. With each, an overactive immune system attacks the body, causing inflammation that can damage skin, joints, and tendons. If left untreated, these conditions can each get progressively worse.
