Overview
Crystal arthritis (gout) is a painful inflammatory condition caused by uric acid crystal buildup in a joint, most often in the foot or ankle. The crystals trigger the immune system and lead to sudden swelling, warmth, and intense pain. Attacks can come on quickly, sometimes even after the joint seemed fine the day before. With proper care, attacks can be controlled and future flares can often be reduced.
Symptoms
People with gout commonly notice sudden, severe joint pain with marked tenderness, redness, and warmth, frequently starting at the big toe but also occurring in the ankle or midfoot. The joint often feels stiff and may be very difficult to tolerate even light touch, such as a bedsheet. Symptoms typically worsen over hours and peak within a day, making walking or standing difficult during a flare. Between attacks, some people have no symptoms, while others develop ongoing joint discomfort.
Causes
Gout happens when uric acid levels in the blood become high enough for crystals to form and deposit in joint tissue. These urate crystals activate inflammation, producing the acute "flare" sensation. Triggers such as alcohol, dehydration, certain foods, illness, or changes in medications that affect uric acid can provoke attacks even if the underlying tendency has been present for a while.
Risk Factors
Your risk is higher if you have elevated uric acid, a history of kidney stones, chronic kidney disease, or metabolic conditions such as obesity and insulin resistance. Certain medicines, including some diuretics (water pills) and low-dose aspirin, can raise uric acid and increase flare risk. Male sex and increasing age are non-modifiable factors, and family history can also play a role. Dehydration and frequent alcohol intake can make attacks more likely.
Prevention
Staying well hydrated can help reduce uric acid concentration and lower flare frequency. Limiting alcohol, especially beer and spirits, and reducing intake of purine-rich foods (such as certain red meats and organ meats) may help prevent recurrences. If you have recurrent gout, taking urate-lowering medication as prescribed and not stopping it during a flare (unless your clinician advises otherwise) is often key to long-term control. Maintaining a healthy weight and addressing blood pressure and blood sugar with your healthcare team can also reduce risk.
How the Diagnosis Is Evaluated
Clinicians usually start with a history of prior attacks, the pattern of onset, and whether the joint looks red, hot, and very tender. A physical exam helps confirm the location and severity of inflammation. The most definitive test is joint fluid analysis to look for monosodium urate crystals, which also helps rule out infection. Blood tests for uric acid support the diagnosis, but uric acid can be normal during an acute flare, so they are not sufficient by themselves. Imaging such as ultrasound or dual-energy CT may be used in some cases.
Nonsurgical Treatment Options
During an acute gout flare, treatment focuses on quickly reducing inflammation and pain using anti-inflammatory medicines such as NSAIDs, colchicine, or corticosteroids. If one or a few joints are involved, an in-office corticosteroid injection into the affected joint can relieve symptoms for many people. Resting the painful joint and using ice packs can help calm discomfort while medicines take effect. For prevention of future attacks, long-term urate-lowering therapy (commonly allopurinol or febuxostat) may be recommended, often along with low-dose preventive medication at the start to reduce early flares. Lifestyle measures such as hydration, moderating alcohol, and weight management can complement medication to lower recurrence.
When to Seek Medical Attention
Seek urgent care or same-day medical attention if you have severe joint pain with fever, feel ill, or suspect infection, because septic arthritis is an emergency. Get prompt evaluation if you cannot bear weight, the swelling is rapidly expanding, or the joint pain is unlike your usual gout flares. Medical attention is also important if you have a first-time attack, if attacks are becoming more frequent, or if you have kidney disease or other major medical conditions that affect treatment choices. If symptoms involve the ability to move the joint significantly or there is numbness, contact a clinician promptly.
Frequently Asked Questions
Common triggers include dehydration, alcohol intake, heavy meals with purine-rich foods, recent illness or injury, and medication changes that affect uric acid levels.
Gout can look very similar to infection because both cause hot, swollen joints, but infection usually requires urgent treatment and is confirmed with appropriate testing, often including joint fluid analysis.
Next Steps
If you suspect gout, schedule a clinical evaluation soon-especially if it is your first attack or you have fever. Ask whether joint fluid analysis is appropriate to confirm the diagnosis and rule out infection. If you have been diagnosed before, follow your flare plan and discuss long-term urate-lowering prevention with your clinician to reduce future recurrences.
