It seems there might be a bit of confusion with the terminology. Psoriatic arthritis (PsA) and rheumatoid arthritis (RA) are two distinct conditions, although they share some similarities. Psoriatic arthritis is an inflammatory autoimmune condition that is associated with psoriasis, which is a skin disease causing red, scaly patches. PsA can cause joint stiffness, pain, and inflammation, similar to RA, but it is also characterized by its connection to psoriasis. If you meant to ask about PsA specifically, it's important to note that it's less common than RA and involves the immune system attacking joint tissues, often alongside skin symptoms.
