My 22 month old son went to the doctor today for fever, diarrhea and cold symptoms. They said he seemed okay but are testing a stool sample because they were concerned about lots of mucus in his BMs. Tonight, when trying to brush his teeth, I noticed that his gums are swollen, purple-red and bleeding. Is it possible that the gum bleeding is related to his other symptoms, or is it some separate gum disease? I'm feeling terrible because I haven't been as pushy about thoroughly brushing his teeth every day as I should (he hates it).
