DD got the herpes virus at about 18 months. It was really horrible with blisters all over the inside of her mouth. She was prescribed liquid Zovirax (which didn't do much I don't think and cost €40 for a bottle!)
She's had one or two coldsores since then but now she's had pretty much recurrent ones for 6 weeks. One will clear up just for another one to develop straight away.
Should she see the GP or is there something I could give her to help?
