Main psoriatic arthritis symptoms include psoriasis plaques on the skin; joint pain and stiffness; swollen fingers and toes; foot pain; and lower back pain.
Psoriatic arthritis can present very differently from person to person. Some patients have more skin involvement; others more joint involvement. Regardless, psoriatic arthritis is a “systemic” disease, which means it can affect your entire body and increase your risk for seemingly unrelated diseases like heart disease, diabetes, depression, and more.
