Kidney stone pain can begin suddenly and become intense enough to interfere with walking, sleeping or everyday activities. Some people experience sharp pain in the side or back, while others feel discomfort that travels toward the lower abdomen or groin.

This pain is often called renal colic. It commonly occurs when a stone moves into the ureter, the narrow tube that carries urine from the kidney to the bladder. A stone can irritate the urinary tract or obstruct urine flow, producing severe, sometimes wave-like pain. (NIDDK)

Finding effective kidney stone pain relief involves more than taking a painkiller. The treatment must also account for the stone's location, the degree of obstruction, kidney function, possible infection and whether the stone is likely to pass naturally.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides evaluation and management of kidney-related conditions, including kidney-function concerns associated with urinary stones.

What Helps Relieve Kidney Stone Pain Quickly?

The most appropriate pain-relief method depends on the person's health, the severity of symptoms and whether complications are present.

Medical approaches may include:

• Prescribed anti-inflammatory pain medicines: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly recommended as first-line treatment for renal colic when suitable for the patient.

• Paracetamol: May be considered when appropriate, depending on the clinical situation and other medicines being taken.

• Stronger prescription pain relief: May be needed in selected cases when first-line treatment is unsuitable or insufficient.

• Treatment of the obstruction: If pain remains uncontrolled, a procedure to relieve obstruction or remove the stone may be necessary.

European Association of Urology guidance recommends NSAIDs as a first-choice option for renal colic when there are no relevant contraindications. Persistent pain despite appropriate medication can require urgent intervention. (EAU Guidelines on Urolithiasis)

Important: Do not take a medicine simply because it worked for someone else. Kidney disease, dehydration, pregnancy, stomach ulcers, blood-thinning medicines and other health conditions can change which painkillers are safe.

Which Painkillers Are Used for Kidney Stones?

There is no single best painkiller for every person with a kidney stone.

1. Nonsteroidal Anti-Inflammatory Drugs

NSAIDs are commonly used for acute renal colic because they reduce pain and inflammation.

Examples include ibuprofen, diclofenac and other medicines in this class. However, they are not appropriate for everyone.

NSAIDs can worsen kidney function in susceptible patients, particularly those with existing CKD, dehydration, reduced kidney blood flow or certain cardiovascular conditions. They may also increase the risk of stomach bleeding and other complications.

People with kidney disease should not self-medicate with NSAIDs without professional advice.

2. Paracetamol

Paracetamol may be an option for some patients, depending on the severity of pain, medical history and other medicines.

It may not provide sufficient relief for every episode of renal colic. Follow professional dosing advice and avoid taking multiple products that contain paracetamol.

3. Prescription Pain Medicines

When pain is severe or other options cannot be used, a clinician may prescribe stronger pain relief.

Some prescription medicines can cause drowsiness, nausea, constipation or breathing-related adverse effects. Their suitability depends on kidney function and the patient's overall condition.

4. Medicines That Help a Stone Pass

In selected patients, a doctor may prescribe a medicine such as an alpha-blocker to help a suitable ureteral stone pass.

These medicines do not directly provide immediate pain relief and are not appropriate for every stone. Their usefulness depends on stone size, location and individual circumstances.

Do not use leftover prescription medicines or start a stone-passage medicine without medical assessment.

Can You Relieve Kidney Stone Pain at Home?

Home measures may provide temporary comfort while you arrange appropriate care, but they cannot reliably remove a stone or resolve a dangerous obstruction.

Use Gentle Heat for Comfort

A warm compress or heating pad placed over the painful area may help some people feel more comfortable.

Avoid excessive heat and do not apply a heating pad directly to bare skin. Heat should never delay medical assessment for severe or worsening pain.

Rest in a Comfortable Position

Find a position that makes the pain more manageable. However, rest alone does not treat the cause of renal colic.

Sip Fluids According to Your Medical Advice

Maintain appropriate hydration, but do not force large quantities of water during a painful episode.

Drinking excessive water will not reliably push an obstructing stone through the ureter. If you have kidney failure, heart failure, fluid restrictions or persistent vomiting, fluid advice needs to be individualized.

Follow Your Prescribed Treatment

If a clinician has assessed your stone and provided a treatment plan, follow the instructions for medication, follow-up and monitoring.

Seek reassessment if pain is worsening, medication is not helping or new symptoms develop.

Does Drinking Water Reduce Kidney Stone Pain?

Not necessarily.

Drinking enough fluid is important for preventing many types of kidney stones and may be recommended when a small stone is being managed conservatively. However, forcing extra water during an acute painful episode is not a proven way to provide rapid relief.

If a stone is obstructing urine flow, excessive fluid intake will not remove the blockage. It may worsen discomfort in some circumstances.

People with kidney failure, advanced CKD, heart failure or a prescribed fluid restriction should follow their clinician's instructions.

Why Does Kidney Stone Pain Come and Go?

Kidney stone pain may fluctuate as the ureter contracts and responds to a moving stone or obstruction.

Pain may:

• Start suddenly

• Become intense and then ease

• Return in waves

• Move from the side or back toward the abdomen or groin

• Occur with nausea or vomiting

The severity of pain does not reliably indicate the stone's size. A relatively small stone in the ureter can cause severe pain, while some larger stones inside the kidney cause few symptoms.

Persistent or uncontrolled pain needs medical evaluation even if it comes and goes.

How Long Does Kidney Stone Pain Last?

There is no fixed duration.

Pain may settle if a stone moves or passes, but it can recur while the stone remains in the urinary tract. The duration depends on stone size, location, obstruction and whether complications develop.

Do not assume that the stone has passed simply because the pain stops. A clinician may recommend follow-up imaging or other testing to confirm that the obstruction has resolved.

When Is Kidney Stone Pain an Emergency?

Seek urgent medical care if kidney stone pain occurs with any of the following:

• Fever or chills

• Very little or no urine

• Severe or persistent pain despite prescribed medication

• Repeated vomiting or inability to keep fluids down

• Fainting, confusion or marked weakness

• Known obstruction with signs of infection

• Rapid deterioration in general health

An obstructed urinary tract combined with infection can become a serious emergency. Urgent drainage using a ureteral stent or nephrostomy may be needed before definitive stone removal. (EAU Guidelines on Urolithiasis)

Do not attempt to manage these warning signs with home remedies or extra painkillers.

What If Kidney Stone Pain Does Not Improve With Medicine?

Uncontrolled pain may mean that the current treatment is insufficient or that the stone requires active intervention.

Depending on the findings, a urologist may recommend:

• Ureteroscopy: A small instrument is passed through the urinary tract to locate and remove or fragment the stone.

• Laser lithotripsy: Laser energy breaks the stone into smaller pieces during an endoscopic procedure.

• Shock wave lithotripsy: Externally generated shock waves break selected stones into smaller fragments.

• Percutaneous nephrolithotomy (PCNL): A procedure used particularly for larger or complex kidney stones.

• Ureteral stenting or nephrostomy: May be required to restore urine drainage when obstruction needs urgent relief.

The procedure depends on stone size, location, anatomy, kidney function, infection status and overall health. Larger stones or stones causing obstruction may require treatment rather than continued attempts at pain control alone. (NIDDK)

How Do Doctors Identify the Cause of Kidney Stone Pain?

A clinical assessment helps confirm whether the pain is caused by a stone and whether there are complications.

Depending on the situation, investigations may include:

Urine tests

• Blood in urine

• Signs of infection

• Other urinary abnormalities

Blood tests

• Serum creatinine and eGFR

• Electrolytes

• Blood count when indicated

• Other tests according to the clinical findings

Imaging

• Ultrasound

• Non-contrast CT when appropriate

• Other imaging in selected circumstances

These investigations help determine the stone's location, size, possible obstruction and effect on kidney function. The choice of imaging depends on factors such as age, pregnancy status and the urgency of the situation.

Kidney Stone Pain Relief in People With Kidney Disease

People with reduced kidney function need extra care when choosing pain medicines.

Some commonly used painkillers may worsen kidney function or cause other complications in susceptible patients. The risk can be higher during dehydration or acute illness.

If you have CKD, a kidney transplant, dialysis dependence or a history of acute kidney injury:

• Do not start NSAIDs without medical advice.

• Tell your clinician about all medicines and supplements you use.

• Follow your prescribed fluid plan.

• Seek prompt assessment for reduced urine output.

• Do not delay treatment for severe pain, fever or vomiting.

Pain management should account for both the stone and the person's underlying kidney condition.

How Can You Reduce the Risk of Another Kidney Stone?

Pain relief addresses the current episode, but prevention can reduce the chance of future stones.

Depending on the stone type and medical history, prevention may include:

• Drinking an appropriate amount of fluid as advised by your clinician

• Reducing excessive dietary sodium

• Following an individualized diet

• Maintaining normal dietary calcium unless advised otherwise

• Taking prescribed preventive medicines when indicated

• Completing stone analysis when a stone is retrieved

• Considering metabolic evaluation for recurrent stones

• Attending follow-up appointments

The best prevention strategy depends on the stone's composition and the person's urine and blood test results. (NIDDK)

Frequently Asked Questions

What is the fastest way to relieve kidney stone pain?

A clinician can recommend appropriate pain medicine based on your health and kidney function. NSAIDs are commonly first-line for renal colic when safe, but severe pain or warning signs require urgent assessment.

Which painkiller is best for kidney stone pain?

NSAIDs are often recommended first when there are no contraindications. Paracetamol or prescription alternatives may be considered according to the clinical situation. People with kidney disease should seek professional advice before taking painkillers.

Can kidney stone pain go away on its own?

It may settle if a stone moves or passes, but pain relief does not prove that the stone has passed or that an obstruction has resolved. Follow-up may be necessary.

Does drinking lots of water flush out a kidney stone?

No. Appropriate hydration can support prevention and may be part of conservative treatment, but excessive water does not reliably force an obstructing stone out.

Can I take ibuprofen for kidney stone pain?

Ibuprofen is an NSAID and may help renal colic in some people. However, it can be unsafe for people with certain kidney conditions, dehydration, stomach ulcers, cardiovascular risks or other contraindications. Ask a healthcare professional before using it.

Why is kidney stone pain so severe?

A stone can irritate or obstruct the ureter, causing intense contractions and pain. Even a small ureteral stone can produce severe symptoms.

When should kidney stone pain be treated in hospital?

Seek urgent care for severe or uncontrolled pain, fever or chills, very little or no urine, repeated vomiting or other signs of serious illness. Infection with urinary obstruction is an emergency.

Conclusion

Kidney stone pain relief depends on choosing safe pain management while identifying whether the stone is likely to pass or requires active treatment. Clinician-recommended pain medicines, temporary comfort measures and appropriate follow-up may help, but home care cannot reliably resolve a blocked urinary tract.

People with kidney disease should be especially cautious with painkillers and fluid intake. Severe pain, fever, chills, repeated vomiting or reduced urine output requires urgent medical evaluation.

For kidney-function assessment and coordinated care for kidney-related concerns, consult Dr. Sandip Prabhakar Bhurke at Prabhakar Bhurke Clinic. When a stone requires a procedure, coordination with an appropriate urology specialist may be necessary.
