OK moms ! I have a serious question. I took my son Jr to urgent care last night because his eye suddenly starting to swell up his eye got really red and he was itchibg his face BAD it looked like he got punched in the eye but without it looking bruised up. the doctor came in looked at his face and said its pink eye and walked out to get me a prescription for eye drops so we were like OK he has pink eye and this morning he woke up and his eye isn't pink isn't red and its not swollen let me just has we recently bought a German Shepherd puppy and Jr has asthma. my question is does pink eye just come in go in a matter of hours or is my son having allergies to his new puppy ? he has a doctors appointment tomorrow but I need some second opinions.
