Gout causes sudden, intense pain and swelling in a joint, often striking without warning in the middle of the night. The pain is severe enough that even the weight of a bedsheet on the affected joint can feel intolerable. Most first attacks hit the base of the big toe, but gout can affect ankles, knees, wrists, fingers, and elbows as well.
What a Gout Attack Feels Like
The hallmark of gout is a flare (also called an attack) that comes on fast. The joint becomes hot, swollen, red, and extraordinarily tender. Many people describe being woken from sleep by the pain, which can go from nothing to excruciating within hours. Walking or putting any pressure on the joint becomes difficult or impossible.
Flares typically start in a single joint. The base of the big toe is the classic location, involved in the first attack for 56 to 78% of patients. Over the course of the disease, that joint is affected at some point in 59 to 89% of people with gout. Other commonly targeted joints include the midfoot, ankles, knees, fingers, wrists, and elbows.
An untreated flare generally peaks within the first 24 hours and then gradually resolves over one to two weeks. Between flares, many people feel completely normal, with no lingering joint symptoms at all. This cycle of intense pain followed by total remission is one of the things that distinguishes gout from other forms of arthritis.
Early Warning Signs Before a Flare
Some people notice subtle sensations in a joint before a full flare develops. These can include mild tingling, stiffness, or a vague sense that something is “off” in the joint. Not everyone experiences these pre-flare signals, and they can be easy to dismiss. But if you’ve had gout before, recognizing that early discomfort gives you a window to start treatment before the pain escalates.
Common Triggers
Gout flares don’t happen at random. They’re driven by a spike in uric acid levels, and certain behaviors reliably raise that risk. Alcohol is one of the best-studied triggers. A large internet-based study tracking recurrent attacks found a clear dose-response relationship: the more alcohol consumed in the prior 24 hours, the higher the risk. Drinking one to two servings of wine more than doubled the odds of a flare. Beer and liquor carried similar risks, with more than two to four servings of either raising attack odds by roughly 67 to 75%.
The risk climbs further when alcohol is combined with foods high in purines (red meat, organ meats, certain seafood like sardines and mussels) or with diuretic use. Dehydration also plays a role, since it concentrates uric acid in the blood. Illness, surgery, and sudden changes in medication can set off attacks too.
How Gout Progresses Over Time
Gout tends to follow a predictable pattern if uric acid levels stay elevated. Early on, flares are infrequent and separated by long symptom-free stretches. Over months or years, attacks may become more frequent, last longer, and involve more joints at once. People with gout tend to have more joints affected per episode than those with other crystal-related joint conditions, averaging around two joints per flare compared to fewer in similar diseases.
Eventually, if uric acid remains high, the crystals that cause gout can form permanent deposits called tophi. These are firm, visible lumps under the skin that range from the size of a pea to as large as a tangerine. They most commonly appear around joints, in cartilage, tendons, and ligaments. But they can also show up in unexpected places: the ears, nose, and even the whites of the eyes. Some tophi develop a white head where uric acid crystite is working its way to the surface. Tophi are a sign that gout has advanced significantly and that crystal deposits need to be reduced aggressively.
Chronic gout can also cause lasting joint damage. The crystals erode cartilage and bone over time, leading to permanent stiffness, reduced range of motion, and visible joint deformity. This stage is largely preventable with treatment, which is why recognizing symptoms early matters.
Gout vs. Pseudogout
Pseudogout can look nearly identical to gout: sudden joint pain, swelling, redness, and warmth. The key difference is the type of crystal involved. Gout is caused by uric acid crystals, while pseudogout comes from calcium pyrophosphate crystals. Telling them apart based on symptoms alone is unreliable.
A few patterns can offer clues. Gout heavily favors men (about 76% of cases), while pseudogout has a more even sex distribution. Gout patients typically have higher blood uric acid levels, averaging around 9.1 mg/dL compared to 6.7 mg/dL in pseudogout. And gout tends to affect more joints per episode. But the only definitive way to distinguish them is by examining fluid drawn from the joint under a microscope: gout crystals are needle-shaped, while pseudogout crystals are rhomboid-shaped.
How Gout Gets Diagnosed
If you show up with a red, swollen, agonizingly painful big toe, gout is high on the list. But confirming it involves more than just looking at the joint. The gold standard is joint aspiration, where a small amount of fluid is drawn from the affected joint and checked under a microscope for uric acid crystals. Finding those crystals is considered definitive proof.
Blood tests for uric acid are helpful but not conclusive on their own. Uric acid crystals begin forming when blood levels exceed roughly 6.8 mg/dL, but some people have elevated uric acid and never develop gout, while others have a flare when their levels test as normal (levels can actually drop during an acute attack). A reading of 8 mg/dL or higher during a workup makes gout more likely, and levels above 10 mg/dL point strongly toward it.
Doctors also weigh the pattern of symptoms: which joints are involved, how quickly the pain peaked, how long episodes last, and whether there’s complete resolution between attacks. Imaging, including ultrasound and specialized CT scans, can reveal crystal deposits in and around joints even between flares, which helps confirm the diagnosis in uncertain cases. The presence of tophi on physical exam is one of the strongest clinical indicators.
What to Watch For Between Attacks
The quiet periods between flares can create a false sense that gout has resolved. In reality, uric acid crystals continue to accumulate in joints even when you feel fine. This is why gout tends to worsen over time without treatment aimed at lowering uric acid levels long-term. If you’ve had one attack, roughly 60% of people will have a second within a year.
Between flares, pay attention to any developing lumps near joints or on the ears. These could be early tophi. Also note whether flares are becoming more frequent, involving new joints, or taking longer to resolve. All of these signal that the disease is progressing and that your uric acid levels need better control. Treatment targets typically aim for blood uric acid below 6 mg/dL, and below 5 mg/dL for people who already have tophi or frequent flares.
