17 month old has fever around 100 degrees, extremely sore mouth, ( will not open to let me see anything) swollen bleeding gums, fatigue, but gets up often in the night and day during naps, and diarreah. She will want a drink of water but scream in pain when she has a sip. Decreased appitite ( assuming because of the sore mouth as she is still interested in good but screams in pain when she has a bite/taste. Help! I giving her Tylenol regularly. Took her to a dr and they were not sure, thought it was viral and said to come back in 3-4 days. I want to make sure they are not missing something
