Understanding Kidney Stone Pain
Kidney stones can cause some of the most severe pain imaginable. The sharp, cramping pain often starts suddenly as stones move into the urinary tract. Kidney stone pain can be completely incapacitating in the moment. But why do these small stones cause such excruciating pain? And how can you get relief?
What Triggers the Pain?
Kidney stones form when minerals crystallize in concentrated urine and clump together. These sharp crystalline structures can be as small as a grain of sand or grow to a few centimeters across. The stones start to cause pain when they break free from the kidney and travel through narrow tubes on the journey out of the body.
As a stone moves from the kidney down the ureter toward the bladder, it has to squeeze through tight spaces. This compression and irritation of sensitive tissues lining the urinary tract triggers incredible muscle spasms and pain signals to the brain.
The Type of Pain
Doctors characterize kidney stone pain as "renal colic." This means it comes in waves, like labor pains during childbirth. The intermittent pains start fast, last an extremely intense 30 to 60 minutes, and then fade. But just when you think it's over, another wave may start.
In between the acute colic attacks, there may be a dull ache or feeling of pressure in your back or side where the stone is passing. This discomfort may come and go until the stone fully clears the urinary tract.
Coping with Kidney Stone Pain Episodes
Dealing with kidney stone pain flares can be a real challenge. During the waves of most intense cramps, it can be impossible to stand up straight, find a comfortable position, or focus on anything else.
Home Remedies Between Attacks
When you have a temporary break between acute waves of stone pain, try these self-care tips:
- Drink plenty of water - Staying hydrated helps stones pass.
- Take over-the-counter pain relievers like ibuprofen or acetaminophen.
- Apply a warm compress or take a warm bath for temporary relief.
- Limit physical activity to rest your body.
Learning coping strategies to distract your mind from the discomfort also helps. Listen to music, meditate, practice deep breathing, or watch television.
Seeking Emergency Treatment for Uncontrolled Pain
If at-home pain relief methods don't work, kidney stone pain may become too intense to manage. Warning signs of uncontrolled pain requiring emergency care include:
- Pain so bad you can hardly stay still
- Pain lasting over an hour that continues to intensify
- Visible blood in the urine
- Nausea and vomiting
- Fever, chills and other signs of infection
During severe kidney stone attacks, emergency room doctors can provide intravenous medications and fluid to ease your discomfort.
Medical Procedures to Manage Pain Episodes
If kidney stones keep getting stuck and causing repeat pain flare ups, additional medical procedures may help. Options include:
- Lithotripsy: Shock wave pulses break up stones so they pass easier.
- Surgery: Endoscopic techniques remove problematic stones.
- Stents: Small tubes help widen the urinary tract so stones pass through.
- Medications: Alph blockers relax muscles for less painful stone passage.
Discuss the benefits and risks of these interventions with your urologist or nephrologist.
When Will the Pain Finally Go Away?
Its hard to predict exactly how long kidney stone pain episodes will last. But most stones do eventually fully clear the urinary system. Heres a timeline of what to possibly expect:
During Active Stone Passage
The most intense pains come in unpredictable waves during active stone passage down the ureter. For medium sized stones of 4-6mm, episodes may last:
- 1-2 weeks for 50% of people
- Up to 4 weeks for 90% of people
- 2-3 months for the remaining 10%
Larger stones over 6mm or stones that become stuck can cause pain over months. Tiny stones less than 4mm may pass quickly in a few days with milder symptoms.
After Full Stone Clearance
Once scan confirm full kidney stone clearance, pain typically goes away completely within 1-2 days. Any residual discomfort or blood usually resolves within a week.
But forstones that caused damage or scarring to delicate urinary tract tissues, some mild lingering pain might come and go for several weeks after stone passage.
Preventing Painful Kidney Stones
About half of people who have experienced one kidney stone report recurrence within 5-7 years without prevention strategies. Unfortunately multiple painful passages are common.
Depending on the mineral composition of your stones, your doctor can prescribe medications or recommend diet and lifestyle changes known to reduce risk. For example:
Diet Modifications
- Drink enough fluids, especially water
- Limit sodium rich foods
- Eat less animal protein
- Avoid excess vitamin C
- Reduce sugary foods and beverages
Lifestyle Changes
- Take prescribed potassium citrate if helpful
- Manage medical conditions causing stones
- Prevent obesity
- Get enough but not excessive calcium
Implementing prevention techniques greatly reduces the chances of going through the misery of kidney stone pain again!
FAQs
Why does kidney stone pain come and go in waves?
The intermittent intense pain, called renal colic, occurs when the stone moves down your urinary tract and gets squeezed in tight spaces. It tries to pass, then gets stuck again, causing another wave.
What helps ease kidney stone pain at home?
Drink fluids, take OTC pain meds, apply heat, limit activity, use coping techniques like deep breathing, meditation and distraction to get through pain episodes at home.
When should you go to the ER for kidney stone pain?
Seek emergency help if pain becomes too severe to stand, lasts over an hour intensifying, you have vomiting, visible bleeding or fever - uncontrolled pain may require IV treatment.
How long will it take to pass a kidney stone?
Small stones may pass in a few days with mild symptoms. Medium 4-6mm stones cause the worst pain for 1-4 weeks typically. Large or stuck stones can cause pain for months until surgical removal.
What can prevent repeat kidney stones?
Diet changes to control sodium, animal protein, sugar and vitamin C intake, medications, weight control and optimal calcium can reduce your risk of developing new painful kidney stones.
