Hello, my 7yr old son has had a high temperature, sore throat and generalised malaise feeling for 3 days, he has been responding well to calpol and neurofen, but I've noticed today that his scrotum is bright red, he's not complaining of pain or tenderness and there's no urinary problems, do I need to seek medical attention for him? I hope I'm worrying over nothing but it looks so unusual, many thanks in advance for your response.
