Breaking Down Kidney Stones: Causes, Symptoms, and Prevention

Few things get someone's attention like the sudden, gripping pain of a kidney stone. Here in the Jacksonville, FL heat, dehydration is a year-round concern, and that makes kidney stones a problem we see often at Reliance Primary & Urgent Care. Understanding how stones form, what they feel like, and how to lower your risk can help you avoid a repeat episode and know when to seek help.

What Are Kidney Stones?

A kidney stone is a hard, crystal-like deposit that forms inside a kidney when certain minerals and salts in your urine become too concentrated. Small stones may pass on their own without you ever noticing. Larger ones can get stuck in the narrow tubes that carry urine from the kidney to the bladder, and that is when the trouble usually starts.

Common Types of Stones

• Calcium oxalate — the most common type, linked to diet and dehydration.
• Uric acid — more likely with high animal-protein intake, gout, or low fluid intake.
• Struvite — often related to certain urinary tract infections.
• Cystine — rare and tied to an inherited condition that causes the kidneys to leak a specific amino acid.

What Causes Kidney Stones?

Stones form when your urine holds more crystal-forming substances (like calcium, oxalate, and uric acid) than the fluid can dilute. Several factors push that balance in the wrong direction.

• Dehydration — the single biggest driver, and a real risk in the Florida climate.
• Diet — high sodium, high animal protein, and very high-oxalate foods can all contribute.
• Family or personal history — if you or a close relative have had stones, your risk is higher.
• Certain conditions — obesity, gout, some digestive diseases, and repeated urinary infections all raise the odds.

The Florida Heat Factor

Jacksonville summers are long, hot, and humid. When you sweat heavily and do not replace those fluids, your urine becomes more concentrated, giving crystals a better chance to clump together. People who work outdoors, exercise in the heat, or simply do not drink enough water are especially vulnerable. If you have had a stone before, staying ahead of your hydration during our warm months is one of the most protective things you can do.

Symptoms to Watch For

Kidney stone pain often comes in waves as the stone moves. Common signs include:

• Severe pain in the side, back, or below the ribs
• Pain that radiates toward the lower abdomen and groin
• Nausea and vomiting
• Blood in the urine (pink, red, or brown)
• Painful or frequent urination, or urine that looks cloudy or smells strong

Because these symptoms can overlap with other conditions, an accurate diagnosis matters. If you are dealing with sudden, significant flank pain, a same-day evaluation at our Jacksonville urgent care clinic can help sort out what is going on.

When It's Urgent Versus a True Emergency

Many stones can be managed with fluids and pain control, but some situations need prompt attention. Seek urgent care if the pain is severe, you cannot keep fluids down, or you see blood in your urine.

Treat it as an emergency and go to the nearest ER or call 911 if you have a fever and chills along with the pain (a possible sign of infection combined with a blocked stone), if you are unable to urinate at all, or if pain is so intense that you cannot function. Reliance is not an emergency room, and an infected, obstructing stone can become dangerous quickly.

How Kidney Stones Are Diagnosed

Diagnosis usually combines your symptoms with a few tests. Imaging such as a CT scan or ultrasound can locate the stone and measure its size. A urine test checks for blood, infection, and crystals, while blood work looks at kidney function and mineral levels. These results guide whether a stone is likely to pass on its own or needs a specialist's help.

Treatment Options

Treatment depends on the size and location of the stone.

• Hydration — drinking plenty of water helps flush smaller stones through.
• Pain management — medications can ease the discomfort while a stone passes.
• Medications — certain drugs relax the urinary tract to help a stone move or help prevent new ones.
• Procedures — larger or stuck stones may need shock wave lithotripsy (ESWL) or ureteroscopy, which are performed by urology specialists.

As your primary care team, we can evaluate you, start supportive care, and coordinate a specialist referral when a procedure is needed.

Preventing Future Stones

If you have had one stone, you are at higher risk for another, so prevention is worth the effort.

• Stay well hydrated — aim for pale-yellow urine, and drink more during hot Florida days and workouts.
• Adjust your diet — lower your sodium, moderate animal protein, and ask about oxalate-rich foods if you form calcium oxalate stones.
• Keep up with follow-up — ongoing monitoring through chronic disease management can catch problems early, especially if you have gout, diabetes, or recurrent stones.

Frequently Asked Questions

How long does it take to pass a kidney stone?

It varies with size and location. Small stones may pass within a few days to a few weeks, while larger ones can take longer or may not pass without treatment. If pain is severe or lingers, get evaluated.

Can drinking more water really prevent kidney stones?

Yes. Good hydration is one of the most effective and simplest prevention strategies, because it keeps your urine diluted so crystals are less likely to form. This is especially important in the Jacksonville, FL heat.

Are kidney stones a sign of a more serious problem?

Usually they are a standalone issue, but recurring stones can point to an underlying condition worth investigating, such as a metabolic or dietary factor. Your primary care doctor can help identify the cause.

Should I go to urgent care or the ER for a kidney stone?

For manageable pain and no fever, urgent care or primary care is a reasonable first stop. If you have a fever, cannot urinate, cannot keep fluids down, or the pain is unbearable, go to the ER or call 911.
