A red, swollen, throbbing toe that flares up, settles just enough to ignore, then flares again. If that cycle sounds familiar, you are dealing with one of the most common foot problems there is, and one of the most commonly mismanaged.
An ingrown toenail happens when the edge of the nail presses into or pierces the skin beside it. The skin reacts the way it would to any splinter: it becomes inflamed, painful and prone to infection. Soaking, antiseptic and careful trimming can settle a mild episode, but when the nail edge itself is the problem, the flare keeps returning until the edge is dealt with.

What is an ingrown toenail?
The clinical name is onychocryptosis. The nail plate, usually on the big toe, grows into the soft nail fold beside it, or the fold swells over the nail edge. Either way the result is the same: pressure, broken skin, inflammation and often infection.
Several things push a nail in that direction. Trimming the corners into a curve rather than cutting straight across. Tight shoes and work boots that squeeze the toes together. Stubbing or dropping something on the toe. Sweaty feet that soften the skin fold. And for many people, simply the inherited shape of the nail, which is why some families see far more of these than others.
If your toe is caught in the flare-and-settle cycle, our podiatry in Mount Gravatt team sees this presentation weekly and can usually tell you within one appointment whether the nail edge needs a permanent fix.
Why does it keep coming back?
Because the flare and the cause are two different things. The pain, redness and swelling are the flare. The cause is a strip of nail edge sitting where it should not sit. Salt-water soaks, antiseptic and better trimming can calm the flare, and for a first, mild episode that may be all you need.
But if the nail edge is curved, damaged or repeatedly pressed in by footwear, the same strip of nail regrows into the same bit of skin every few weeks or months. People often spend a year or more in this loop, managing each flare and dreading the next, without knowing a definitive option exists.
How common is it?
Antibiotics are not the fix
Research summarised in American Family Physician found that oral antibiotics before or after definitive nail-edge treatment did not improve outcomes. The mechanical problem needs the mechanical fix.
Teenagers and young adults are the most commonly affected group, though we see ingrown nails at every age, from school shoes through to work boots and beyond.

Do antibiotics fix an ingrown toenail?
This surprises almost everyone: no, not on their own. An infected ingrown nail can genuinely need antibiotics to control the infection, and that is a decision for your doctor. But the research summarised above found that antibiotics did not improve the outcome of definitive treatment, because the nail edge that caused the broken skin is still there when the script runs out.
Treating an ingrown toenail with antibiotics alone is like treating a splinter with antibiotics and leaving the splinter in.
What actually helps?
It depends on the stage, which is exactly what an assessment sorts out.
Early or mild: straight-across trimming, footwear with room in the toe box, salt-water soaks during a flare, and techniques a podiatrist can show you to keep the skin fold off the nail edge. Many first-time episodes settle well with this.
Recurrent or severe: the definitive option is a minor in-clinic procedure called a partial nail avulsion, where the offending sliver of nail edge is removed under local anaesthetic and the nail root at that edge is treated with a chemical called phenol so the strip does not regrow. It is done in the clinic room, you walk out afterwards, and the published evidence supports it as an effective way to stop the cycle. It is a far smaller event than most people imagine when they hear the words nail surgery.
When should you seek help?
A first mild episode in a healthy person can reasonably be managed at home for a few days. Beyond that, earlier assessment saves toes a lot of misery.
Consider getting assessed if
The toe is increasingly red, swollen or weeping; there is spreading redness or you feel unwell; this is your second or third flare; you have diabetes or reduced circulation, in which case any broken skin on the foot deserves prompt professional care; or the pain is changing how you walk or what shoes you can wear.
