Q.
Is it Psoriatic Arthritis? Why Your Joints Ache & Expert Medical Steps
A.
There are several factors to consider. Psoriatic arthritis is an autoimmune cause of inflammatory joint pain that often occurs with psoriasis or nail changes, brings morning stiffness over 30 minutes and swelling that eases with movement, and benefits from early rheumatology care with medicines like NSAIDs, DMARDs, and biologics plus lifestyle steps to prevent joint damage. See below for the full symptom checklist, risk factors, how doctors diagnose and rule out lookalikes, urgent red flags, and expert next steps including how to prepare for your visit and a helpful symptom check before speaking with a clinician.
