Bladder pain: what’s causing it and what to do now

Sharp, burning, or dull aching low in the belly — that’s bladder pain. It can come from a simple urinary tract infection (UTI) or from conditions like interstitial cystitis, bladder stones, or pelvic floor tension. The goal is to stop the worst symptoms fast and get the right tests so you don’t miss something that needs treatment.

Quick at-home steps you can try today

1) Drink plain water. Stretching your urine volume by sipping water can flush bacteria and dilute irritants. Don’t overdo it, but keep steady fluids. 2) Cut bladder irritants for a few days: caffeine, alcohol, citrus, and spicy foods often make pain worse. 3) Use heat. A warm heating pad on your lower belly eases muscle spasm and gives quick relief. 4) Over-the-counter pain relief like acetaminophen or ibuprofen can help. Follow the label and check with your pharmacist if you have health conditions.

5) Try timed voiding. Empty your bladder on a schedule to reduce urgency and retrain bladder signals. 6) If you have pelvic tightness, gentle pelvic floor stretches or seeing a pelvic floor physical therapist can make a big difference for chronic pain.

When to see a doctor and what they’ll check

See a clinician if you have fever, severe pain, blood in urine, nausea/vomiting, or symptoms that don’t improve in 48–72 hours. Your provider will usually start with a urinalysis and urine culture to spot infection. Imaging (ultrasound) or a cystoscopy may follow for repeated or unexplained pain.

Treatments can range from a short course of antibiotics for a UTI to bladder-relaxing drugs for other causes. For example, flavoxate is one option to ease bladder spasms — read our guide on how flavoxate can help veterans and others with urinary stress: Flavoxate for Veterans: Tackling Urinary Stress from War.

If infection is suspected, antibiotics are commonly used. Not all bladder pain needs antibiotics; that’s why testing matters. For recurring issues, doctors may suggest lifestyle changes, physical therapy, or specialized medications. We also have resources on antibiotic choices when needed—see our article about alternatives if your provider discusses options: Keflex Alternatives in 2025.

Don’t ignore severe or repeated bladder pain. If you see blood, high fever, fainting, or can’t urinate, head to urgent care or the ER right away. For ongoing, lower-level pain, tracking triggers, practicing bladder-friendly habits, and working with your clinician will usually get you back to normal.

If you’re unsure what’s happening, save a symptom log (when pain starts, foods you ate, how much you drank) and bring it to your appointment — it helps your clinician diagnose faster.
