You went to bed fine. At two in the morning the big toe joint woke you up: red, hot, swollen, and so painful that the weight of the sheet was unbearable.
That description is gout until proven otherwise. It is one of the few conditions in the foot where the story alone points so strongly in one direction.
What is happening
Gout is a form of inflammatory arthritis caused by monosodium urate crystals forming inside a joint. Urate is a normal waste product; when the level in the blood stays high enough for long enough, it can crystallise, and the immune system reacts to those crystals violently.
Hence the pattern: rapid onset, usually overnight, reaching maximum intensity within a few hours to a day, with the joint visibly red and hot and the skin sometimes peeling as it settles. An untreated attack typically resolves over one to two weeks, which is why people often conclude it was a one-off.
The first metatarsophalangeal joint — the big toe joint — is affected most often, but the midfoot, the ankle and the heel all occur.
What it gets confused with, and one that matters
- Septic arthritis. ⚠ A hot, swollen, extremely painful joint can be an infection inside the joint, and that is an emergency. If you have a fever, feel unwell, or the redness is spreading up the foot, this needs same-day medical assessment. Do not wait to see whether it settles like the last one.
- Bunion pain or joint arthritis, which can flare and look inflamed.
- Cellulitis, a skin infection, which is red and hot but generally more diffuse than a single joint.
- Pseudogout, a different crystal, more common in the knee and wrist.
- A stress fracture or trauma, where there is a mechanism to explain it.
What a podiatrist does with it
The clear split is worth stating, because it sets expectations.
Diagnosis and medication are medical. Confirming gout means blood tests and sometimes joint aspiration, and the urate-lowering treatment that actually prevents future attacks is prescribed and monitored by your GP. Your podiatrist will say so and refer rather than manage around it.
The foot is podiatry. During an attack, that means offloading the joint so you can walk — footwear that does not press on it, padding, sometimes a stiffer sole or a CAM boot to stop the joint bending. Rest, elevation and ice, and not pushing through it.
Between attacks, it means the consequences. Repeated attacks damage the joint surface, and a big toe joint that has lost range changes how you push off, which loads the ball of the foot and can produce callus, forefoot pain and altered gait. That is treatable, with footwear changes and orthotics that reduce demand on the joint.
Long-standing gout can also produce tophi — firm deposits of urate under the skin, often around the toes or the Achilles — which ulcerate under pressure. Those need protecting.
⚠ If you have diabetes as well, do not manage a red, hot foot at home. The overlap between a gout flare, an infection and a foot at risk is exactly where serious problems begin. Book a diabetic foot assessment or see your GP promptly.
Frequently asked questions
Is gout diagnosed by a podiatrist?
Your podiatrist will recognise the pattern and can examine the joint, but confirming gout means a blood test for urate and, in an uncertain case, aspirating the joint to look for crystals. That is your GP's territory, and the long-term medication that lowers urate is prescribed by them. What a podiatrist manages is the foot: offloading the joint, footwear, and the joint damage that repeated attacks leave behind.
Why does it always hit the big toe?
The first metatarsophalangeal joint is the most common site by a wide margin. It is cooler than more central joints, and urate crystallises more readily at lower temperatures, which is thought to be a large part of why the extremities are affected first. It is not the only site — the midfoot, ankle and knee all get involved.
Is a normal urate level proof it is not gout?
No, and this catches people out. Urate can be normal or even low during an acute attack, because the urate is in the joint rather than the blood. A normal level taken mid-attack does not exclude gout, and the test is more informative repeated once things have settled.
Can diet fix it?
Diet is worth attention and it is rarely the whole answer. Most urate is produced by the body rather than eaten, so people who make significant dietary changes often still get attacks. Diet is one lever among several, and where attacks are recurrent the conversation with your GP about urate-lowering medication is the one that changes the trajectory.
How do I know it is not an infection?
You often cannot tell them apart by looking, which is exactly why a hot, swollen, exquisitely painful joint — particularly with a fever, or if you are unwell with it — needs same-day medical assessment rather than an assumption. Septic arthritis destroys a joint quickly and is the diagnosis that must not be missed.
