Hi Aimsmum, hows your dd?
Didn't mean to be scary but my dd started off just exactly the same the week before christmas and had also not be overly well beforehand.
She just kept getting worse and worse, her lips and mouth kept swelling, ulcers came everywhere in her mouth, her throat got very infected and her tonsils got so big they nearly touched. She couldn't eat, drink or take medicine, took a big temperature that wouldn't respond and then after two days an all over body rash which started to blister as did her lips. We had Christmas in the hopsital.
I hope your dd is just fine, I'm probably just a bit sensitive to hear about swollen lips......
