What to do if…
you notice sudden back pain with fever and urinary symptoms starting

Short answer

Get medical care today. Fever/chills with flank (side/back) pain plus urinary symptoms can be a kidney infection and should be evaluated promptly.

Do not do these things

  • Do not delay “to see if it passes” if you have fever/chills plus flank/back pain and urinary symptoms.
  • Do not take leftover antibiotics or someone else’s antibiotics.
  • Do not mask symptoms by taking extra doses of OTC pain/fever medicine beyond the label directions.
  • Do not drive yourself if you feel faint, confused, very weak, or the pain is severe.
  • Do not assume it’s only back strain when urinary burning/urgency/frequency or blood/cloudy urine are also present.

What to do now

  1. Decide: ER/911 now vs same-day urgent visit.
    • Call 911 or go to the ER now if you have confusion/mental changes, severe shortness of breath or very fast breathing, severe dehydration (e.g., cannot keep fluids down due to vomiting), severe pain, or you are not peeing / peeing very little, or you feel rapidly worse.
    • Otherwise, get same-day evaluation via urgent care, your doctor’s office, or the ER (whichever can see you fastest).
  2. Use clear words when you call or check in. Say: “fever/chills + flank/back pain + urinary symptoms (burning/urgency/frequency)” and when it started.
  3. Take 60 seconds to gather information that speeds care.
    • Your temperature (if you can check it).
    • Any blood in urine, nausea/vomiting, and whether you’re pregnant or could be pregnant.
    • Medical conditions that raise risk (for example kidney disease, diabetes, immune suppression) and any antibiotic allergies.
  4. Do only basic self-care while you’re getting seen.
    • Sip water if you can keep fluids down.
    • Use OTC pain/fever medicine only as directed on the label and only if it’s normally safe for you.
    • Have someone stay with you or check in regularly if you feel very ill.
  5. If you use telehealth, make sure it leads to same-day in-person evaluation if needed.
    • With fever + flank pain, telehealth is most useful if it quickly directs you to same-day in-person exam and urine testing (and any other tests the clinician feels are needed). If that can’t happen promptly, choose urgent care/ER instead.

What can wait

  • You do not need to figure out the exact cause right now — focus on getting evaluated.
  • You do not need to make decisions about work, travel, or long-term outcomes today beyond arranging safe, prompt care.
  • You do not need to try multiple home remedies or supplements before being seen.

Important reassurance

This combination of symptoms can feel intense and scary. Many causes are treatable, and getting evaluated quickly is the safest way to reduce the chance of complications.

Scope note

This is first steps only. Follow the clinician’s instructions after evaluation, and seek urgent re-evaluation if you worsen or don’t improve.

Important note

This is general information, not medical advice or a diagnosis. If symptoms are severe, rapidly worsening, or you have signs of serious illness, call 911 or go to the nearest ER.
