Took dd (13) to a walk in centre today as her lower eyelid is swollen, sore and red. She's also come up with a cold sore today. The 'emergency practitioner' said that cold sores couldn't spread to the eye and that it looked inflamed so for her to take an antihistamine and if it starts getting gunky go to the pharmacist for some eye drops. It hasn't helped, it looks just as swollen if, not more. we think we can see maybe the beginning of a blister or it could just be a stye but I'm a bit worried. Should I be? Her eye itself is beginning to go a bit red. We waited 2 hours this morning, so I don't know whether I should phone out of hours, or let it be. Were we given good advice? Am I overreacting?
