Thanks for any help. My son is 4 years old, last night he was crying his legs hurt I couldn’t see anything just thought he was putting off sleep. Today he’s come up in a rash on his legs and chest. He’s still crying and saying his legs and arms hurt. He’s fine apart from this. No temp, no cough, no sickness. Eating and drinking running around. I’ve messaged the dr online but I’m waiting for a response. I just don’t like to see him in pain if there is something I could do. Or any idea what it is. The rash definitely fades when pressed. He doesn’t limp or anything. He did say he has pineapples growing on his back. And has it he’s a little bit but not much. Any help I would appreciate. Thank you
