DS1 is 4.5 years. He's had a sore throat since Friday evening, and woke up yesterday morning with his face puffed up and covered in red blotches. He has pinprick rash over his upper body, a slight cough and was sick last night. No temperature. He's a bit tired but otherwise seems OK in himself.
Any idea what he's got and whether I need to get him to a doctor?
Thanks.
