Good evening. Son is 3 years old. He says it hurts a little below the ear. What could it be? I called an ambulance, they connected me with the head physician. She said to do dry heat, give paracetamol or ibuprofen. And tomorrow go see a ENT doctor. But he's not calming down. What can be done so that he can sleep well at night? And so that it doesn't hurt.
