Kidney stone pain can be sudden and extremely intense. It often begins in the side or back and may move toward the lower abdomen or groin as a stone travels through the urinary tract.
People searching for kidney stone pain relief medicine often want to know which tablet will provide the fastest relief. However, the appropriate medicine depends on factors such as:
-
Stone size and location
-
Severity of pain
-
Kidney function
-
Presence of infection
-
Other medical conditions
-
Pregnancy
-
Medicines the patient already takes
Doctors may use pain-relieving medicines, and in selected situations other treatments may be used to help a stone pass or remove it.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized assessment of kidney stones, kidney function and related complications.
Why Do Kidney Stones Cause Such Severe Pain?
A kidney stone may cause pain when it moves from the kidney into the ureter.
The ureter is a narrow tube that carries urine from the kidney to the bladder. A moving stone can irritate the ureter and interfere with urine flow.
This can produce renal colic, which may cause:
-
Severe flank pain
-
Pain that comes in waves
-
Pain radiating toward the groin
-
Nausea
-
Vomiting
-
Restlessness
-
Blood in urine
-
Urinary urgency
The intensity of pain does not always indicate the size of the stone.
Which Medicines May Be Used for Kidney Stone Pain?
Doctors may use analgesic medicines to control renal colic.
Nonsteroidal Anti-Inflammatory Drugs
NSAIDs are commonly used for renal colic in appropriate patients because they can reduce pain and inflammation associated with ureteric obstruction.
However, they are not suitable for everyone.
Extra caution is needed in people with:
-
Reduced kidney function
-
Chronic kidney disease
-
Previous kidney injury
-
Stomach ulcers or gastrointestinal bleeding
-
Certain cardiovascular conditions
-
Some medication interactions
-
Dehydration
A doctor should determine whether an NSAID is appropriate.
Other Pain-Relief Medicines
When NSAIDs cannot be used or do not provide adequate relief, another analgesic may be considered based on the patient's medical condition.
The choice and dose should be determined by a healthcare professional.
Do not combine multiple painkillers without medical advice.
Why Should People With Kidney Disease Avoid Self-Medicating?
A medicine that is safe for one person may be inappropriate for another.
For example, certain painkillers can reduce blood flow to the kidneys and may worsen kidney function in susceptible patients.
This is particularly important if you already have:
-
High creatinine
-
Reduced eGFR
-
Chronic kidney disease
-
Dehydration
-
A single functioning kidney
-
Previous acute kidney injury
If you have known kidney disease, tell your doctor before taking any pain-relief medicine.
Can Paracetamol Be Used for Kidney Stone Pain?
Paracetamol may be used for pain in certain circumstances, depending on the patient's health and the severity of symptoms.
However, severe renal colic may require a different approach.
The appropriate medicine and dose should take into account:
-
Kidney function
-
Liver health
-
Other medicines
-
Total daily dose
-
Other medical conditions
Do not exceed the recommended dose or combine products containing the same active ingredient.
Does Pain Medicine Remove the Kidney Stone?
No.
Pain-relief medicine can reduce symptoms, but it does not necessarily remove the stone.
The stone may:
-
Pass naturally
-
Remain in the kidney
-
Move into the ureter
-
Cause obstruction
-
Require a procedure
The appropriate treatment depends on the stone's size, location, anatomy and associated complications.
Medicines That May Help a Stone Pass
In selected patients, doctors may prescribe medicines intended to relax the ureter and facilitate passage of certain stones.
These medicines are not appropriate for every stone.
Their usefulness depends on factors such as:
-
Stone location
-
Stone size
-
Patient characteristics
-
Degree of obstruction
-
Presence or absence of infection
A scan can help determine whether medical expulsive treatment is appropriate.
Why Imaging Matters Before Choosing Treatment
When kidney stone pain occurs, doctors may recommend imaging to determine:
-
Stone size
-
Stone location
-
Degree of obstruction
-
Number of stones
-
Kidney swelling
-
Other urinary abnormalities
Ultrasound may be useful in many situations.
CT imaging may provide more detailed information when required.
Treatment decisions should not be based only on pain intensity.
How Long Does Kidney Stone Pain Last?
Pain duration varies significantly.
A small stone may pass spontaneously, while a larger or obstructing stone may remain for longer.
Pain may stop temporarily even when the stone has not passed.
Therefore, disappearance of pain does not always prove that the stone has been eliminated.
Follow-up imaging may be recommended when clinically appropriate.
What Can You Do at Home While Waiting for Medical Care?
For a known uncomplicated stone, your healthcare professional may recommend:
-
Taking prescribed pain medicine
-
Following the recommended fluid plan
-
Monitoring urine if instructed
-
Taking prescribed stone-passage medicine
-
Attending follow-up appointments
Do not force excessive amounts of water to try to push a stone through the urinary tract.
If there is significant obstruction, vomiting, kidney disease or another complication, excessive fluid intake may not be appropriate.
Can Drinking More Water Relieve Kidney Stone Pain?
Water does not directly act as a painkiller.
Adequate fluid intake can be important for preventing future stones and may be part of the management of selected uncomplicated stones.
However, drinking very large amounts of water during severe obstruction can be inappropriate and may worsen discomfort.
Follow the fluid instructions provided by your doctor.
When Is Kidney Stone Pain an Emergency?
Kidney stone pain requires urgent medical assessment when it occurs with signs of infection or significant obstruction.
Seek urgent medical attention for:
-
Fever
-
Chills
-
Severe or worsening pain
-
Persistent vomiting
-
Very little or no urine
-
Severe weakness
-
Confusion
-
Fainting
-
Known obstruction with infection
-
A single functioning kidney with significant symptoms
An infected obstructed urinary system can become a medical emergency.
What If Kidney Stone Pain Comes With Fever?
Fever with suspected kidney stone should not be ignored.
A stone can obstruct urine drainage while bacteria remain within the urinary system.
In this situation, antibiotics alone may not always be enough if urine drainage is blocked.
Urgent medical treatment may involve restoring urinary drainage and treating the infection.
Do not wait for the stone to pass naturally if you have fever and severe stone symptoms.
When Does a Kidney Stone Need a Procedure?
A procedure may be considered when:
-
The stone is unlikely to pass
-
Pain cannot be controlled
-
There is persistent obstruction
-
Kidney function is affected
-
There is recurrent infection
-
The stone is large
-
The stone is causing significant hydronephrosis
-
The patient has a solitary functioning kidney
-
The stone remains despite appropriate observation
Treatment options may include:
Ureteroscopy
A thin instrument is passed through the urinary tract to reach the stone. The stone may be fragmented using laser energy and removed.
Shock-Wave Lithotripsy
Shock waves are used to break the stone into smaller pieces that can pass through the urinary tract.
Percutaneous Nephrolithotomy
PCNL is commonly considered for larger or complex kidney stones. The stone is accessed through a small tract created through the skin into the kidney.
The best procedure depends on stone characteristics and patient anatomy.
Kidney Stone Pain Relief and Kidney Function
People with reduced kidney function require particular caution when selecting pain medicines.
If you have:
-
High creatinine
-
Chronic kidney disease
-
Dialysis treatment
-
A kidney transplant
-
A single functioning kidney
tell your healthcare professional before taking over-the-counter painkillers.
Medication selection may need to be adjusted according to kidney function.
What Happens After the Stone Passes?
Passing a stone does not necessarily mean the problem is over.
Depending on the situation, doctors may recommend:
-
Stone analysis
-
Blood tests
-
Urine testing
-
Metabolic evaluation
-
Imaging
-
Dietary changes
-
Preventive medicines for selected patients
Understanding why the stone formed can help reduce recurrence.
How Can Future Kidney Stones Be Prevented?
Prevention depends on the type of stone and individual risk factors.
General measures may include:
Maintain Appropriate Fluid Intake
Adequate fluid intake can help reduce the concentration of stone-forming substances in urine.
The appropriate amount should be individualized.
Reduce Excess Salt
High sodium intake can increase urinary calcium in some people and contribute to stone risk.
Follow Stone-Specific Dietary Advice
Depending on the stone type, doctors may recommend changes involving:
-
Sodium
-
Animal protein
-
Oxalate-rich foods
-
Calcium intake
-
Purine intake
Avoid unnecessary dietary restrictions without professional guidance.
Treat Metabolic Abnormalities
Some people with recurrent stones have abnormalities in urine chemistry that can be treated with specific dietary or medical measures.
Can Kidney Stone Pain Be Confused With Other Conditions?
Yes.
Severe flank or abdominal pain can also occur with:
-
Kidney infection
-
Appendicitis
-
Gallbladder disease
-
Musculoskeletal problems
-
Gynecological conditions
-
Gastrointestinal disorders
-
Other urinary conditions
The location and pattern of pain alone cannot establish the diagnosis.

Frequently Asked Questions
What is the best kidney stone pain relief medicine?
Doctors commonly consider anti-inflammatory pain medicines for renal colic when appropriate, but they are not safe for everyone. People with kidney disease, dehydration or certain other conditions may need alternative treatment.
Can painkillers remove kidney stones?
No. Painkillers control discomfort but do not necessarily remove the stone.
Can I take painkillers if I have high creatinine?
Do not self-medicate. Some painkillers can worsen kidney function in susceptible people. Consult a healthcare professional before taking them.
Does drinking lots of water help kidney stone pain?
Not necessarily. Excessive water is not a substitute for treatment and may be inappropriate when significant obstruction is present.
Can a small kidney stone pass without surgery?
Some small stones can pass naturally. Whether observation is appropriate depends on the stone's size, location, symptoms, kidney function and presence of obstruction or infection.
When does kidney stone pain require urgent treatment?
Severe pain with fever, chills, persistent vomiting, very little urine or known obstruction requires urgent medical assessment.
What happens if kidney stone pain suddenly stops?
Pain may stop because the stone has moved or passed, but symptoms can also temporarily improve while the stone remains. Follow-up may be necessary to confirm resolution.
Conclusion
Finding the right kidney stone pain relief medicine can make renal colic more manageable, but pain control is only one part of kidney stone treatment. The appropriate medicine depends on kidney function, other health conditions, current medications and the clinical situation.
Some stones pass naturally, while others require medicines, shock-wave treatment, ureteroscopy, laser lithotripsy or PCNL. Fever, urinary obstruction, persistent vomiting, reduced urine output or uncontrolled pain can indicate a complication requiring urgent assessment.
If you are experiencing recurrent or severe kidney stone pain, seek professional evaluation rather than repeatedly relying on over-the-counter painkillers.
