hey, so my daughters had a bad cough, and it sounds like something needs to come up but nothing ever does. sometimes when she breathes it sounds like stuff needs to come up, she's really fussy but still playful, and says she's hungry but doesn't eat much, and she feels hot, and her cheeks are red but the thermometers either show no fever or just a small one. she's also had a little diarrhea and only poops like once a day, she also has a runny nose but at the same time she sounds congested. I took her to the doctor but he said she's fine and probably just has bad allergies or a small cold and gave me recommendations for cough syrup and allergy medicine. it's been a 2 or 3 weeks since she got sick and week since she saw a doctor and it's still going on. anyone know what's wrong? should I take her back?
