Why Kidney Stone Pain Comes and Goes
Urine carries waste chemicals. Healthdirect says they can clump into hard crystals. Stones in the kidneys or ureters can cause severe pain that comes and goes. Doctors call this renal colic. It's typically felt on one side of the back, the side, the lower tummy or the groin.
Because the pain can ease and then return, you may feel fine one hour and unable to work the next. A GP takes that pattern into account when deciding on a sick leave certificate.
- Pain that eases, then returns
- Feeling sick or vomiting
- Blood in your urine
- Needing to pass urine often or urgently
How a Kidney Stone Consult Runs
Your consult starts on the phone, and the GP decides whether to switch to video. For someone under 18, the consult is by phone or video, as the GP decides, with a parent or guardian present.
Stones Vary a Lot in Size
Size varies a lot. Kidney Health Australia describes them as hard, rock-like crystals, ranging from as small as a grain of sand to the size of a golf ball. Healthdirect's symptom list also includes nausea, vomiting, blood in the urine, and a frequent or urgent need to go. Tell the GP about any of them.
Pain Severity That Requires an Emergency Department
Healthdirect advises seeing a doctor as soon as possible for renal colic. If the pain is very severe, go to your nearest emergency department. Go straight away if you have renal colic and signs of infection, such as a fever.

| Symptoms of renal colic | See a doctor as soon as possible |
| Very severe pain | Nearest emergency department |
| Renal colic with signs of infection | Doctor or hospital emergency department straight away |

Why Prompt Care Matters
The page also warns that a stone can block urine flow, cause infection, or scar a ureter. Those are the reasons behind the prompt-care advice in that table.
Not a Substitute
A certificate consult isn't a substitute for that care, and your GP will refer you if your symptoms point to it.
Call 000 in an emergency. OMC Health does not provide emergency care.
Short Episodes and Long Ones
Short episodes and long ones look different on a certificate. A GP may certify a few days.
A Fresh Assessment
If the stone hasn't passed and the pain keeps returning, expect a fresh assessment, because each one is a snapshot of that day.
Time Off While a Stone Passes
Healthdirect says most kidney stones pass on their own in your urine, which can take up to 6 weeks. Kidney Health Australia gives a similar range of three to six weeks.
You won't necessarily be off work for all of that time. The GP considers how often the pain returns, how you're sleeping and what your job involves.
Between Bouts
Say a warehouse worker spent a night in hospital and went home with the stone still to pass. Evenings since have been rough. Mornings are tolerable. By afternoon, the pain builds.
The Useful Question
The useful question isn't how long stones take in general. It's what this person can safely do between bouts, and for how many days.

Tests and Treatment Behind the Paperwork
Healthdirect lists blood tests, urine tests, and imaging, such as CT scans, ultrasound, or X-rays, as ways doctors check for stones. The same kinds of scans appear on Kidney Health Australia's page.
Stones That Pass
For stones that pass on their own, Kidney Health Australia says the only treatment needed is pain relief. Healthdirect also recommends plenty of clear fluids, such as water.
Stones That Won't Pass
Stones that won't pass may need a procedure, including laser treatment or other methods that break the stone into fragments small enough to pass.
What the GP Can Use
None of that is for a telehealth GP to arrange. The GP can use your paperwork: scan results, discharge notes, or a follow-up plan. It shows what was found and what's happening next. That helps the GP decide how many recovery days are reasonable and whether your requested dates fit the picture.
What to Have Ready Before a Kidney Stone Consult
A few minutes of preparation helps.
The dates the pain started and when it was worst.
Whether you attended hospital, and any letter or discharge summary.
Which parts of your job are hard right now, such as lifting, driving or long shifts.
How your sleep has been, since night-time pain can drain you the next day.
What your employer or workplace policy asks for.
Not sure what your workplace wants? The Fair Work Ombudsman's test is whether the evidence would satisfy a reasonable person that you were genuinely entitled to the leave. A medical certificate is one way to meet it.
Physical Work and Hydration After an Episode
Dehydration is named by Kidney Health Australia as a common cause of kidney stones. Healthdirect recommends drinking plenty of fluids every day to keep your urine clear.
Outdoor and Hot Jobs
That can be harder in some jobs. If you work outdoors, in heat or somewhere with limited breaks, talk to your employer about access to water.
Heat and Sweat
The same group also says hot climates and heavy sweating raise the risk.
Other Risk Factors
Healthdirect also names other risk factors: a diet high in salt and meat, lots of fizzy drinks, an earlier stone, and a family history. Its prevention tips include a fibre-rich diet and less salt. Your regular doctor can go through what applies to you.
The GP can note any short-term work limits, where the assessment supports them.

Frequently asked questions
View all FAQsYes, if the GP's assessment supports it. If the hospital didn't give you a certificate, or you need more time off after discharge, a GP can assess your recovery. Share what the hospital found and any follow-up plans. The GP certifies the dates their assessment supports, which may include the days you were in hospital.
It can cover either, depending on the assessment. Some people need time off during the painful episode itself. Others feel drained for a day or two after the pain settles, especially after a hospital visit. The GP asks how you're managing now and certifies the period that's clinically supported.
Possibly. At booking, choose the backdated request add-on and explain the dates you were unwell. Past days are certified only if the GP is satisfied they can be, and hospital or scan paperwork helps. Paying for the add-on doesn't mean those dates will be covered, so book as soon as you can.
No. The certificate is about your capacity to work during the dates certified, not proof of the stone itself. Any scan results or hospital notes help the GP understand the episode. Your employer receives only the dates and the GP's details, not your diagnosis or test results.
Severe back, side, or tummy pain can have several causes, and a telehealth consult can't examine you. If you haven't been diagnosed yet, get an in-person assessment first, and use emergency care for pain you can't bear. A certificate consult is most useful once the cause has been assessed.

Kidney stone pain, called renal colic, is often severe and can come and go. Very severe pain, or pain with a fever, needs an emergency department. Once you've been assessed, a GP can consider how the episode affects your work and issue a certificate if appropriate.
