Does your big toe hurt when you push off, feel stiff first thing in the morning, or ache on top of the joint in tight shoes? Most people assume they are developing a bunion, or that it must be gout.
Often it is neither. The most common cause of a stiff, sore big toe is arthritis in the joint at its base, known as hallux rigidus. It has a clear pattern, and there is a lot that can be done about it well before anyone talks about surgery.

What is hallux rigidus?
Hallux rigidus is osteoarthritis of the first metatarsophalangeal joint, the joint where your big toe meets your foot. As the joint surface changes, the toe becomes progressively stiffer and more painful, especially in the direction that matters most, bending upward.
That upward bend is not optional. The big toe needs to lift roughly 60 degrees for a normal push-off when you walk. When it cannot, your foot quietly finds a way around the problem, usually by rolling to the outside, and that is where secondary aches often start.
How is it different from a bunion?
They get confused constantly, but they look and feel different.
- Bunion: the big toe drifts sideways toward the smaller toes, and a bump develops on the inside edge of the foot
- Hallux rigidus: the toe stays reasonably straight but becomes stiff, and any bump tends to sit on top of the joint rather than the side
- Bunion pain is often about rubbing and pressure, while hallux rigidus pain is usually about movement and push-off
Gout is a different picture again, typically a sudden, intensely painful, hot and red joint rather than a slow stiffening over months or years.
How common is it?
Very common, and more common than people expect once they get past 50.
The most common arthritic condition of the foot
Population imaging studies report considerably higher rates of joint changes, which means many people have changes on a scan without significant symptoms.
That last point is worth holding onto. Changes on a scan do not automatically mean pain, and pain does not automatically mean surgery.
What does it feel like?
People with hallux rigidus often describe:
- Pain right at the base of the big toe, especially when pushing off or going up on the toes
- Stiffness that is worst in the morning or after sitting
- A bump or thickening on top of the joint that catches in shoes
- Difficulty with squatting, lunging, hills or stairs
- Aching elsewhere in the foot from rolling to the outside to avoid the toe
What helps a stiff big toe?
Many people improve with conservative care, and the aim is to reduce what the joint is being asked to do while keeping you moving. A plan often includes:
- An assessment to confirm the diagnosis and measure how much movement the joint has
- Footwear changes, particularly a stiffer sole or a rocker profile that reduces how far the toe has to bend
- Orthotic or in-shoe changes to offload the joint
- Load management, adjusting the activities that consistently flare it rather than stopping everything
- Targeted mobility and strength work for the foot, calf and ankle
- A clear referral pathway if symptoms are advanced and not settling
Our podiatry in Mount Gravatt service can assess the joint and get footwear and loading right for people across Brisbane's southside.
When should you seek help?
Consider getting assessed if
Consider getting assessed if your big toe is stiffening, if push-off hurts, if you are avoiding certain shoes or activities, or if you have started noticing pain elsewhere in the foot. A sudden, very painful, hot, red and swollen big toe joint is a different presentation and should be reviewed promptly by your doctor.
