Is It Rheumatoid Arthritis or Gout? 

Learn the difference between gout and rheumatoid arthritis – symptoms, causes and treatments. 

Question: I am a 50-year-old man recently diagnosed with rheumatoid arthritis (RA). But I have had joint symptoms for some time, beginning two years ago with a bout of excruciating pain and swelling in my left toe and progressing to episodes of pain and swelling in my feet, knees and wrists. While these incidents may have been early signs of rheumatoid arthritis, gout is also a concern of mine. Do you think I have arthritis or gout? 

Answer: It sounds to me like you have gout, an inflammatory disease that occurs when excess uric acid (a bodily waste product) circulating in the bloodstream is deposited as sodium urate crystals in certain joints. 

The excess uric acid may be caused by genetic factors or kidney disease. The condition may be aggravated by certain drugs such as diuretics or by consuming too much alcohol or foods rich in purines, which are broken down into uric acid. 

If your physician didn't know about your previous problems, it's not surprising he diagnosed your condition as rheumatoid arthritis. In its later stages, gout can look a lot like RA, causing pain and inflammation in multiple joints. 

But the causes and treatments are entirely different. Unlike gouty arthritis, RA occurs when the body’s immune system mistakenly attacks the thin membrane that lines the joints. RA may begin acutely in many joints or start gradually in several joints causing damage and pain.  

Gout, on the other hand, often starts as your problem did – with excruciating pain and swelling in the big toe – and often follows a trauma such as an illness or injury. Subsequent attacks may occur off and on in other joints – primarily those of the foot and knee – before becoming chronic. In its chronic stage, gout can affect many joints, but this can take a few years to happen. 

Gout is a well-understood and highly treatable disease. Medications are available to stabilize uric acid levels and relieve acute pain and inflammation. With appropriate treatment gout can be controlled and future flares prevented. Taking the proper medications and taking them faithfully – even during periods when you feel absolutely fine – is essential to controlling gout. Maintaining a reasonable weight and limiting alcohol consumption can help control gout as well. 

If you haven't already had a joint fluid sample examined for urate crystals, I would recommend you speak to your doctor about having one at your next visit. Or if the medication he has prescribed for your RA (and I assume he has prescribed one or more) doesn't seem to be helping, schedule a visit sooner. It is important to determine whether you have rheumatoid arthritis or gout – the sooner you know and begin proper treatment, the sooner you will experience relief.
