[18F] Experiencing severe back pain, urinary symptoms, and systemic signs of infection

What might be happening

Based on the symptoms you've described, there are several possibilities:

• Urinary Tract Infection (UTI): This is an infection in any part of your urinary system, which includes your kidneys, bladder, ureters, and urethra. UTIs are more common in women, and they can cause symptoms like a constant need to urinate, pain or a burning sensation during urination, lower abdominal pain, and lower back pain. However, you mentioned that your UTI test was negative.

  • Treatment for a UTI typically involves antibiotics to kill the bacteria causing the infection.

• Kidney Stones: These are hard deposits made of minerals and salts that form inside your kidneys. They can cause severe pain in your back and sides, below your ribs, and radiating to your lower abdomen and groin. Other symptoms can include persistent need to urinate, pain during urination, and nausea.

  • Treatment for kidney stones varies depending on the size of the stone. Small stones can often pass on their own with plenty of fluids, while larger stones may require medical intervention.

• Gastroenteritis: This is an inflammation of the lining of the intestines caused by a virus, bacteria or parasites. It can cause symptoms like nausea, vomiting, diarrhea, abdominal pain and cramping, bloating, and loss of appetite.

  • Treatment for gastroenteritis usually involves rest, hydration, and over-the-counter medications to relieve symptoms.

• Hyperthyroidism: This is a condition in which your thyroid gland produces too much of the hormone thyroxine. It can accelerate your body's metabolism, causing unintentional weight loss, increased thirst, sweating, and irritability.

  • Treatment for hyperthyroidism can include medication, radioactive iodine, and sometimes surgery.

Please note that these are only possibilities and not a definitive diagnosis. It's important to consult with a healthcare provider for an accurate diagnosis and treatment.

What you can do

1. Continue taking the antibiotics as prescribed by your doctor.
2. Stay hydrated, especially if you're experiencing increased thirst and frequent urination.
3. Rest as much as possible to help your body recover.
4. Avoid any foods or drinks that seem to make your symptoms worse.
5. Keep a symptom diary to track your symptoms, which can help your healthcare provider make a diagnosis.

What you should look out for

Seek immediate medical attention if:

• Your symptoms get worse or don't improve after a few days.
• You have severe abdominal or back pain.
• You have a high fever.
• You're unable to keep down fluids due to vomiting.
• You notice blood in your urine or stool.

Remember, it's important to consult with a healthcare provider for an accurate diagnosis and treatment.
