Gout
Crystals inflaming a joint Uric acid builds up in the blood over years and forms needle-shaped crystals in a joint. The body reacts to the crystals, and that reaction is the pain and swelling.

Gout vs Ingrown Toenail
Gout is a joint problem, not a skin problem. Uric acid crystals form inside the big toe joint, and the whole joint turns red, hot and swollen, usually overnight. An ingrown toenail is a skin problem at the edge of the nail. One corner of the nail digs in, and only that corner is sore. The location of the pain is a useful clue: gout often affects the joint at the base of the toe, while an ingrown nail irritates the nail fold. Location alone cannot confirm the cause.

Ingrown Toenail
Side by side
The differences that matter
What it is
Gout
Crystals inflaming a joint
Uric acid builds up in the blood over years and forms needle-shaped crystals in a joint. The body reacts to the crystals, and that reaction is the pain and swelling.
Ingrown Toenail
The nail corner growing into skin
The edge of the nail pushes into the soft skin fold beside it. The skin reacts the way it would to a splinter. Nothing is infected at the start.
What it looks like
Gout
The whole toe joint red and swollen
Shiny, dusky red or purple skin over the base of the big toe, and a joint that looks two sizes too big. The skin often peels as the flare settles.
Ingrown Toenail
Red, puffy skin beside the nail
The nail itself looks normal. The skin at one corner is swollen and shiny, sometimes with a bead of yellow fluid.
Where it hurts
Gout
The knuckle at the base of the toe
The joint where the toe meets the foot. The nail end of the toe usually feels fine.
Ingrown Toenail
The corner of the nail
The tip of the toe, on one side only. Pressing that corner reproduces the pain exactly.
How it starts
Gout
Suddenly, often at night
Many people go to bed well and wake at two in the morning unable to bear the weight of a sheet.
Ingrown Toenail
Builds over days
Tender first, then sore in shoes, then throbbing. There is usually a week of warning.
How much it hurts
Gout
Severe, even a bedsheet is too much
The joint is exquisitely tender to the lightest touch, and walking is difficult during a flare.
Ingrown Toenail
Sore on one spot
Uncomfortable in a tight shoe, and tender when the corner is pressed. Bearable in an open shoe.
What it does over time
Gout
Settles in a week or two, then returns
A flare fades on its own, and between flares the toe feels normal. Untreated, flares come back and can involve other joints.
Ingrown Toenail
Worse until the pressure changes
It will not settle while the nail is still digging in. Left alone, the skin piles up over the edge and can start to weep.
Treatment
Gout
Anti-inflammatory medicine, then prevention
A flare is calmed with anti-inflammatory medicine. Repeat flares are prevented with a daily tablet that lowers uric acid, which is a long-term treatment rather than a course.
Ingrown Toenail
Take the pressure off the edge
Warm salt-water soaks, roomier shoes, and a clinician lifting or trimming the corner. A stubborn one is treated by numbing the toe and removing a narrow strip of nail edge.
When it needs a doctor
Gout
Yes, gout needs to be diagnosed
A first flare should be confirmed rather than guessed at, because the treatment that prevents the next one depends on blood tests and a proper diagnosis.
Ingrown Toenail
If there is pus or it keeps returning
Worth a visit if the fold is oozing, if lumpy pink tissue has grown over the nail edge, or if the same toe goes ingrown again and again.
Gout is not a skin condition
Gout
The skin over a gouty joint is a passenger. It turns red, shiny and warm because of the inflammation underneath, and it often peels for a few days as the flare fades. That peeling is sometimes mistaken for a fungal or eczema patch.
Long-standing gout can show on the skin. Firm chalky lumps called tophi can build up over joints, on the tops of the feet, and on the edges of the ears. Those are deposits of the same crystals, and they are a sign the uric acid level has been high for a long time.
When a hot joint needs urgent care
Common questions
Questions Patients Ask
How do I tell gout from an ingrown toenail?
Press two spots. Gout hurts at the joint where the big toe meets the foot. An ingrown toenail hurts at the corner of the nail. The two problems sit at opposite ends of the same toe.
Can gout affect the toenail?
Not directly. Gout is inflammation inside the joint, and the nail is not involved. The skin over the joint can redden and peel, but the nail itself looks normal.
Why does gout start at night?
Body temperature drops slightly during sleep, which makes uric acid crystals more likely to form in a joint. That is why many flares wake people in the early hours.
Does an ingrown toenail ever swell the whole toe?
It can, once it becomes infected, but the redness still centres on the nail fold. Swelling that wraps around the joint at the base of the toe points elsewhere.
How long does a gout flare last?
Most flares settle over one to two weeks, and the toe feels normal in between. Without treatment they tend to come back, often more often over time.
Which doctor handles which?
Gout is usually managed by a family doctor or a rheumatologist, with blood tests to guide it. An ingrown toenail is handled by a podiatrist or a dermatologist.
Safety to keep in mind
A painful, swollen joint can also be infected. Seek urgent medical care if the pain is worsening or you also have fever, chills or feel unwell. A first possible gout attack needs a medical assessment rather than a diagnosis from a picture.
