I’m crying watching my 2 year old struggle to sleep because he’s so stuffed up and congested

I’m just here to rant honestly. My son has been sick before, a few times. But he’s never been THIS congested. He’s so stuffed up, he has a terrible cough. We took him to urgent care and they said his lungs sound clear and they think it’s just viral. My poor baby is literally crying saying my nose is stuffy. I feel so terrible! I wish there was something I could do to make him feel better! I tried a steam shower, we’re doing lots of liquids. But obviously it just has to run its course.
