Picking at the skin or nails is a habit that many people recognise in themselves but rarely talk about. For some, it is an occasional habit triggered by stress. For others, it becomes a repetitive pattern that damages the nail bed, causes pain, and increases the risk of infection. This is often referred to as onychotillomania, a condition that falls under the broader group of body focused repetitive behaviours.
This article looks at what nail picking is, why it happens, the risks involved, and the treatment options available through a podiatrist in Sydney, particularly when the habit affects the toenails as well as the fingernails.
What Is Nail Picking?
Nail picking refers to the repeated picking, tearing, or peeling of the nails or the skin surrounding them. It is closely related to nail biting but tends to involve the fingers pulling or scratching at the nail plate and cuticle rather than the teeth. Nail pickers may target loose bits of skin, hangnails, or the edges of the nail itself, sometimes to the point of causing bleeding or visible damage.
While occasional picking at a rough nail edge is common and generally harmless, onychotillomania describes a pattern that is persistent, difficult to control, and causes noticeable damage to the nail or surrounding tissue over time.
How Nail Picking Differs from Nail Biting
Nail biting, medically known as onychophagia, involves biting the nail itself with the teeth. Nail picking is a separate behaviour that usually involves the fingers manipulating the nail, cuticle, or surrounding skin. The two habits can occur together, and both are classed as body focused repetitive behaviours, but the physical damage they cause can differ. Picking tends to affect the nail bed and surrounding skin more than the nail plate itself, which can lead to different complications such as skin infections or changes in nail growth.
Common Causes of Nail Picking
There is rarely a single cause behind picking at fingernails. In most cases, it develops from a combination of psychological habits and physical triggers.
Psychological and Behavioural Triggers
Many people who pick at their nails describe doing so when they feel anxious, bored, or under pressure. The behaviour can become an automatic response that provides a temporary sense of relief or distraction, even though it is not consciously chosen. Over time, this can turn into a habit that continues even in low stress situations, simply because the pattern has become ingrained.
Body focused repetitive behaviours like nail picking are sometimes linked to broader patterns of anxiety or perfectionism, where a person feels the need to smooth away any imperfection they notice on their nails or skin.
Underlying Skin or Nail Conditions
Physical factors can also play a role. Dry skin, hangnails, eczema around the fingertips, or minor nail irregularities can give someone a reason to start picking. Once the skin is broken, healing can be slower, which creates more rough edges and more opportunities to keep picking. This cycle can make the habit harder to break without addressing both the behaviour and the underlying skin condition.
Signs You May Be a Nail Picker
The habit can range from mild to severe. Common signs include:
- Regularly picking at the skin around the nails, even when nails are already short or smooth
- Visible redness, soreness, or bleeding around the nail bed
- Nails that appear uneven, ridged, or thickened from repeated trauma
- Spending noticeable time picking without full awareness of doing so
- Feeling unable to stop despite wanting to
Recognising these patterns is the first step towards managing the habit before it leads to more serious complications.
Risks and Complications of Picking at Fingernails
While nail picking might seem like a minor habit, repeated damage to the nail and surrounding skin can lead to a number of complications.
| Risk | Description | Potential Outcome |
|---|---|---|
| Skin infection | Broken skin around the nail allows bacteria to enter | Redness, swelling, and in some cases paronychia (infection around the nail fold) |
| Nail bed damage | Repeated trauma to the nail matrix affects how the nail grows | Ridged, thickened, or irregularly shaped nails |
| Delayed healing | Constant picking reopens wounds before they can heal | Chronic soreness and ongoing skin breakdown |
| Fungal infection | Damaged nails and skin are more vulnerable to fungal entry | Discoloured or brittle nails that are harder to treat |
| Permanent nail changes | Long term damage to the nail matrix | Nails that grow back thin, split, or misshapen |
For most people, the physical risks are manageable if the habit is addressed early. Left untreated over months or years, however, the nail bed can sustain lasting damage.
When Picking Affects Toenails: The Danger of a Ripped Toenail
While nail picking is often discussed in relation to fingernails, some people also pick, pull, or tear at their toenails, particularly if a nail is loose, ingrown, or has become thickened. This can be more serious than picking at fingernails because toenails endure constant pressure from footwear and body weight.
Someone who has managed to rip a toenail off, whether through picking or an accidental knock, is left with an open wound at the nail bed. This creates a real risk of infection, especially in enclosed shoes where the environment is warm and moist. It can also be extremely painful and take weeks to properly heal. If a toenail has been torn or partially removed, it is worth having it assessed rather than continuing to pick at the remaining nail or surrounding skin, as this can disrupt healing and increase the chance of the nail regrowing abnormally.
Podiatrists regularly see patients who have caused further damage by trying to manage a torn or ingrown toenail themselves. Our article on Ingrown Toenail Treatment in Sydney explains how these nail conditions are assessed and managed, along with the factors that can contribute to ongoing nail pain and injury.
How to Stop Picking Fingernails
Breaking the habit usually requires a combination of practical strategies and, in some cases, professional support.
Self Care Strategies
- Keep nails trimmed short and smooth so there is less to pick at
- Moisturise hands and cuticles regularly to reduce dryness and hangnails
- Wear plasters or gloves during high risk times, such as while watching television or working at a desk
- Replace the habit with a less damaging one, such as fidgeting with a small object
- Keep nails and hands out of sight during moments of stress or boredom, where possible
These steps can help reduce the physical triggers that encourage picking, but they do not always address the underlying behavioural pattern.
When to See a Professional
If picking has caused ongoing pain, bleeding, infection, or visible nail damage, it is worth seeking professional care rather than relying on self care alone. This is particularly important if the habit involves the toenails, where the risk of infection is higher due to footwear and the position of the feet.
A podiatrist can assess the current state of the nail and skin, treat any infection or damage that has already occurred, and provide practical advice on protecting the nail bed while it heals. In cases where the picking is closely tied to anxiety or stress, a podiatrist may also recommend working alongside a GP or psychologist to address the behavioural side of the habit.

Our clinics across Sydney are set up to assess and treat these issues in a comfortable, professional environment, using sterile instruments and evidence based techniques.
If picking, biting, or tearing at your nails has left you dealing with pain, infection, or nails that are not growing back properly, professional care can help. Get in touch with our team today at Sydney City Podiatry to book an assessment at one of our Sydney clinics.
Frequently Asked Questions
1. Is nail picking the same as onychotillomania?
Onychotillomania is the clinical term used to describe persistent, repetitive picking or pulling at the nails that causes noticeable damage. Occasional picking at a rough edge is common, but onychotillomania refers to a more consistent and difficult to control pattern.
2. Can picking at fingernails cause permanent damage?
Repeated picking can damage the nail matrix, which is responsible for nail growth. Over time, this can lead to nails that grow back ridged, thickened, or irregularly shaped. Early intervention reduces the likelihood of lasting changes.
3. What should I do if I rip a toenail off?
If you rip a toenail off, clean the area gently, cover it with a sterile dressing, and avoid tight footwear while it heals. It is a good idea to have the nail assessed by a podiatrist, particularly if there is significant pain, swelling, or discharge, as these can indicate infection.
4. Why do people pick at their nails when stressed?
For many people, picking becomes an automatic response to anxiety, boredom, or stress. It can provide a brief sense of relief or focus, even though it is not a conscious decision. Over time, the behaviour can become habitual rather than a deliberate choice.
5. When should I see a podiatrist about nail picking?
If picking has led to ongoing pain, bleeding, signs of infection, or visible changes to how the nail is growing, it is worth having it assessed. This is especially important for toenails, where infection risk is higher due to enclosed footwear.
6. Can a podiatrist treat the habit itself, or only the physical damage?
A podiatrist focuses on treating and managing the physical damage to the nail and surrounding skin, including infection, ingrown nails, and abnormal regrowth. Where the habit appears to be linked to stress or anxiety, a podiatrist may suggest additional support from a GP or psychologist to address the behavioural component.
