Psoriatic arthritis and rheumatoid arthritis: how they differ

Both conditions may cause tender, swollen joints and morning stiffness. Rheumatoid arthritis often affects matching joints on both sides, particularly small hand and foot joints, while psoriatic arthritis may affect an uneven pattern, the spine, or an entire finger or toe. These are clues, not rules.

Psoriasis, nail pitting, heel pain, or a sausage-shaped finger can support psoriatic arthritis. Rheumatoid arthritis can occur without psoriasis and may be associated with persistent hand or wrist symptoms. Blood tests and imaging can support assessment, but no single result settles every case.

Write down which joints hurt or swell, whether symptoms are symmetrical, how long morning stiffness lasts, and whether movement improves it. Mention psoriasis, nail changes, eye symptoms, bowel symptoms, family history, and previous treatments. Bring photographs of visible swelling when it comes and goes.

Early review helps clinicians protect joint function and choose an appropriate plan. Anti-inflammatory medication may ease symptoms but does not replace evaluation of ongoing inflammation. Gentle range-of-motion work can help, while a painful swollen joint should not be repeatedly forced.

Arrange prompt assessment for persistent swelling, increasing morning stiffness, or new difficulty gripping, walking, or climbing stairs. Seek urgent help for a hot swollen joint with fever, sudden severe eye pain or vision change, new weakness, or rapidly worsening function.

Which features point toward psoriatic arthritis or rheumatoid arthritis? Do I need blood tests or imaging? How will we monitor inflammation and joint function? What can I safely use for symptom relief while assessment continues?
