Please help!!

Emily

I’m writing about my niece. She’s 15 months old. She has had to have Tylenol and Motrin everyday, every four hours because she has had some illness for over a month now. Every time we go to the doctor they always say it’s viral. They never test her for anything but the flu and it always comes back negative. She has a constant fever, coughing, and acts like she’s in pain. We even took her to the ER all they did was swan her for the flu, which came back negative, told her it was viral, and sent her home. Can anyone help!! This baby is absolutely sick and I feel so bad for her so if anyone has any suggestions please feel free to share them
