What to do for my 2-year-old nephew with hydrocele, pain, swelling, and fever for 3-4 days?

Hydrocele in a 2-year-old, along with pain, swelling, and fever lasting 3-4 days, could be concerning. The presence of fever and significant discomfort suggests a possible infection or secondary complication, such as an incarcerated hernia or testicular torsion, both of which require prompt attention. It’s important not to delay in seeking medical care, as these conditions can become serious quickly without intervention. I would recommend you to take your nephew to a healthcare provider or nearby emergency department as soon as possible. There, a doctor will likely perform a physical examination, and may order an ultrasound or other imaging studies to evaluate the hydrocele and surrounding structures. These steps will help rule out any serious underlying conditions and ensure appropriate treatment. In the meantime, ensure your nephew is kept comfortable. Avoid applying any cream or substances to the swollen area without medical guidance. Also keep him hydrated and monitor his temperature. Over-the-counter medications like acetaminophen (if he is using it previously and without any adverse reactions) may help reduce fever and alleviate pain temporarily, but these must be used only according to pediatric dosing guidelines. Yet, these are only temporary measures and should not delay seeking urgent medical advice.
