[6M] With fever, headache, and left flank pain

What might be happening

Based on the symptoms you've described for your son - fever, headache, and pain to the touch on the left side of his flank - here are a few possibilities:

• Urinary Tract Infection (UTI): UTIs are common in children and can cause fever, abdominal pain, and sometimes headaches. They're typically caused by bacteria and require antibiotics for treatment.

• Kidney Infection (Pyelonephritis): This is a specific type of UTI that affects the kidneys. It can cause fever, flank pain, and sometimes headaches. It's a serious condition that needs immediate medical attention.

• Appendicitis: This is an inflammation of the appendix, a small organ on the right side of the abdomen. It typically causes pain on the right side, but in some cases, the pain can be felt elsewhere. It's a medical emergency that requires immediate attention.

What you can do

Given the symptoms you've described, it's important to seek immediate medical attention for your son. Here's what you can do:

1. Take your son to the nearest emergency department or urgent care center. If his pain is severe or his condition worsens rapidly, call an ambulance.

2. Keep him hydrated and comfortable. Avoid giving him any food or drink if you suspect appendicitis, as this could complicate potential surgery.

What you should look out for

Watch out for these symptoms, as they could indicate a more serious condition:

• Severe or worsening pain
• Vomiting
• Blood in the urine
• Inability to pass urine
• Extreme fatigue or lethargy
