<human>: My four year old son a hour ago started making alot of saliva , this is not normal for him he has not drooled since he was a toddler , I have him laying up now on couch to sleep so I can watch him , could it be a cold? or something worse, he is responsive as he always is, just keeps getting mouth full of spit and its watery not thick at all
<bot>: Hi...probably he is having difficulty in swallowing and this could be the first sign of a viral or bacterial pharyngitis. Because of pain while swallowing he might not be swallowing the Silva and this shy he might be Chat Doctor. I suggest you to wait and watch as he is otherwise active. But if he develops fever or sore throat - then I suggest you get a rapid streptococcal antigen testing done at the pediatricians office and proceed further. Regards -
