A sudden, sharp pain radiating from the back can be alarming and is often mistaken for a routine muscular issue. However, in many cases, it may be one of the early signs of kidney stones—a painful condition that affects a large number of individuals each year. Recognising these symptoms early is essential for timely diagnosis and effective treatment.
Kidney stones are small, hard deposits of minerals that form in the kidneys. They don’t usually cause any noticeable symptoms at first. In the summer, when dehydration makes it more likely for stones to form, they happen more often. These crystalline deposits may not make any noise at first, but as they move through the urinary tract, they can cause sudden and severe kidney stone symptoms.
This sudden pain and discomfort can quickly get in the way of daily life, making what seems like a small problem into a medical emergency that needs to be dealt with right away. Knowing the early warning signs and when to see a doctor are very important for managing kidney stones and avoiding problems.
What Are Kidney Stones?
Kidney stones are hard pieces that form in the kidneys from minerals and salts. When minerals like calcium, oxalate, and uric acid build up in urine and then harden, they form kidney stones.
Kidney stones can be very small, like a grain of sand, or very big, like a stone. They can block the flow of urine. When a stone moves from the kidney to the ureter, which is a tube that carries urine from the kidney to the bladder, it can cause many of the usual signs and symptoms of kidney stones.
Kidney stones are more likely to occur if a person is dehydrated, has a certain dietary habit, is overweight, suffers from certain medical conditions, or has a family history of kidney stones.
Symptoms of Kidney Stones Explained
Severe pain is the first sign of kidney stones. However, the signs and symptoms may be different depending on how big the stone is.
Here are some of the most common signs and symptoms of kidney stones that you should be aware of.
Severe Pain in the Back or Side
The first sign of kidney stones is a sharp pain in the lower back or side, just below the ribs. As the stone moves through the body, the pain can be very bad or very mild.
The pain may persist for several minutes or hours.
Pain That Spreads to the Lower Abdomen or Groin
The pain can also be felt in the lower abdomen or groin as the stone passes through the system. The pain can be felt as a deep cramping pain that increases over time.
Blood in the Urine
Another sign is blood in the urine. This is called haematuria in the medical world. The stone may irritate the blood, which can make the urine look pink, red, or brown.
Even small stones can make blood show up in the urine as they move through the urinary tract.
Pain or Burning While Urinating
There are instances when a person may be feeling some form of pain when urinating due to the presence of a kidney stone in the lower part of the urinary tract. This is similar to the feeling that a person gets when he or she is infected with a urinary tract infection.
Frequent Urge to Urinate
When a kidney stone is near the bladder, it may cause an individual to experience the urge to urinate. However, the individual may urinate in small amounts.
Cloudy or Foul-Smelling Urine
In some cases, the presence of a kidney stone may cause changes in the appearance of the urine. This is usually the case when an infection is involved.
Nausea and Vomiting
Nausea and vomiting are common symptoms experienced by people who have kidney stones. The symptoms occur especially when the pain is severe. The reason for this is that the kidneys and the digestive system are connected by nerves.
Fever and Chills
When a kidney stone presents itself along with fever and chills, this is a sign that there is a severe infection in the urinary tract. Such a condition requires urgent medical attention.
Early Signs of Kidney Stones
Sometimes, the early symptoms experienced by people who have kidney stones can be very mild and can easily be ignored. It is important to identify the early symptoms in order to avoid future complications. The early signs that people who have kidney stones can experience include:
- Mild pain in the back or side
- A burning sensation while urinating
- Frequent urination
- Slightly pink or cloudy urine
- Nausea or mild stomach discomfort
The symptoms start before the actual movement of the stone and the severe pain that follows.
Where Does Kidney Stone Pain Occur?
The pain can be felt in different places depending on the position of the stone in the urinary system.
The common places where pain is felt are:
- Flank (side of the body): pain felt on either side of the back below the ribs
- Lower back: pain felt in the lower back region
- Lower abdomen: pain felt that radiates towards the stomach region
- Groin: pain felt in the groin or pelvic region
- Testicles (men only): pain felt in the testicular region for men when the stone passes through the ureter
Types of Kidney Stones
Knowing the type of kidney stone is crucial in determining the best treatment and prevention measures.
Calcium Stones
The most common type of kidney stone, usually made of calcium oxalate crystals, and is often related to dehydration and diet.
Uric Acid Stones
Kidney stones that form if urine is too acidic, usually in people with high protein intake.
Struvite Stones
Kidney stones are usually related to urinary tract infections and have a high rate of growth.
Cystine Stones
A rare type of kidney stone, usually resulting from a genetic disorder that causes an excess of cystine in urine.
When Should You See a Doctor?
There are instances when it is best to seek medical attention for a kidney stone.
If you are experiencing:
- Severe pain that makes it difficult to sit or find a comfortable position
- Presence of blood in the urine
- Fever with chills
- Nausea with vomiting
- Difficulty urinating
- Presence of pain with signs of infection
- Then it is best to seek medical attention.
Causes and Risk Factors of Kidney Stones
Identifying the causes of kidney stones can also help you prevent them from occurring again.
Some of the common risk factors for kidney stones are:
Dehydration
One of the most common causes of kidney stones is not drinking enough water. This causes the urine to become concentrated, resulting in the formation of stones.
Diet High in Sodium or Oxalates
A diet that is high in sodium or contains many foods with oxalates, such as spinach or nuts, can also lead to the formation of kidney stones.
Obesity
Excessive weight can also affect the chemical composition of urine, thereby increasing the risk of kidney stones.
Family History
If you have a family member who has had kidney stones before, you are also at an increased risk of getting them.
Certain Medical Conditions
Medical conditions such as repeated urinary tract infections, gastrointestinal disorders, or metabolic disorders can also lead to the formation of kidney stones.

Treatment Options for Kidney Stones
Treatment depends on the size, location, and severity of the stones.
Small stones may pass on their own with increased fluid intake and pain relief. Larger stones may require medical intervention.
Kidney stones are treated with the following options:
- Medications to relax the ureter muscles, helping the stones pass.
- Extracorporeal shock wave lithotripsy, where shock waves are used to break stones into smaller pieces.
- Ureteroscopy, where stones are removed from the ureter.
- Percutaneous nephrolithotomy is used for removing larger stones.
We recommend the best course of treatment depending on your condition.
Tips to Prevent Kidney Stones
Prevention of kidney stones is all about simple lifestyle changes.
Some useful tips for the prevention of kidney stones are:
- Drink plenty of water during the day
- Reduce your sodium level
- Reduce the level of oxalate-containing foods
- Maintain a healthy weight
Frequently Asked Questions (FAQs)
The initial symptoms include sharp pain in the lower back or sides, a burning sensation during urination, and frequent urination. In addition, a person can experience mild nausea or slightly pink urine. These symptoms can start as minor but increase in severity as the stone travels.
Kidney stone pain is usually very painful and comes in waves. It typically starts in the back or side and sometimes moves to the lower abdomen or groin area. It is usually considered one of the worst types of pain, and it is usually difficult to sit still or get comfortable.
Yes, smaller kidney stones can pass on their own with enough fluids and time. However, the process can still be painful. Larger stones may not pass naturally and often need medical treatment to avoid complications or prolonged discomfort.
Both may cause discomfort during urination, but in the case of a kidney stone, there may be severe back or side pain, as well as blood in the urine. Infections may cause burning, urgency, and fever. A medical test is necessary to confirm.
It depends on the size and location of the stone. Some small stones may pass within a few days, but larger stones may take weeks or may not pass at all. The pain may fluctuate during this time as the stone moves.

Conclusion
Kidney stones may form again if the underlying causes are not addressed. This is because 50% of patients may form another stone within a few years. This emphasizes the need to recognize the signs of a kidney stone as soon as possible. However, prevention of kidney stones cannot be overemphasized.
Simple prevention measures such as increased intake of fluids and diet can play a great role in reducing the risk of kidney stones. More importantly, prevention helps in avoiding complications such as infections and damage to the kidneys.
With modern, minimally invasive treatments available, early diagnosis not only relieves symptoms faster but also improves long-term kidney health.
Kidney Stone Prevention Guide – Practical Diet & Hydration Recommendations
If you are prone to kidney stones or are trying to avoid them, then small changes in your daily routine can help. This guide provides you with practical and precise numbers to follow.
Diet: What to Eat and What to Limit
- Sodium: Keep intake below 2,300 mg per day (ideally closer to 1,500 mg if at risk). Avoid processed foods, packaged snacks, and excess salt.
- Calcium: Aim for 1,000–1,200 mg per day from food sources like milk, curd, or paneer. Do not avoid calcium unless advised.
- Oxalates: Limit high-oxalate foods like spinach, nuts, beetroot, and chocolate. Do not eliminate completely—balance matters.
- Protein: Keep animal protein moderate (about 0.8–1 gram per kg body weight daily). Excess red meat can increase risk.
- Sugar: Reduce added sugars and sugary drinks, which can increase stone risk.
- Fruits: Include citrus fruits like lemon and orange daily—they help reduce stone formation.
Hydration: How Much Water Do You Really Need?
- Drink enough fluids to produce at least 2–2.5 litres of urine daily (usually requires about 2.5–3 litres fluid intake).
- In hot climates or heavy sweating, increase intake to 3–3.5 litres per day.
- Urine should be pale yellow or almost clear—this is a simple hydration check.
- Spread water intake evenly; avoid drinking large amounts at once.
- Include lemon water or coconut water occasionally for added benefits.
- Limit sodas and sugary beverages as they increase stone risk.
Simple Daily Routine
- Start your day with 1–2 glasses of water.
- Drink a glass of water every 1–2 hours.
- Add lemon to one glass daily.
- Carry a 1-litre bottle and refill it 2–3 times.
- Do not ignore thirst or delay urination.
These are general recommendations. Always consult your doctor for personalised advice, especially if you have a history of kidney stones.
