Gout is an inflammatory arthritis, but it is not the same as rheumatoid arthritis (RA), osteoarthritis or other causes of joint pain. If symptoms are new or unclear, start with how gout is diagnosed and the broader gout symptoms guide rather than trying to diagnose the arthritis type from one symptom alone.
Gout vs. rheumatoid arthritis
Gout often causes sudden attacks in one joint, especially the big toe, ankle or knee. RA more often causes persistent inflammatory pain and swelling in multiple joints, frequently in a symmetrical pattern involving hands and wrists. Either disease can become more widespread over time.
Gout vs. osteoarthritis
Osteoarthritis usually causes more gradual mechanical pain, stiffness and reduced movement. Gout can occur in a joint that also has osteoarthritis, so the two diagnoses are not mutually exclusive.
Other conditions that can look like gout
CPPD (pseudogout), septic arthritis, cellulitis, bunions, tendon problems and injuries can all resemble parts of a gout flare.
What tests help?
Serum urate, inflammatory markers, rheumatoid-factor or anti-CCP testing and imaging can help depending on the differential diagnosis. When gout remains uncertain, identifying monosodium urate crystals in joint fluid is the most definitive test.
Why not diagnose yourself from the location alone?
A swollen big toe strongly suggests gout, but location is not proof. Likewise, hand pain does not automatically mean RA. The more atypical or persistent the presentation, the more important a proper clinical evaluation becomes.
