Hi, in December, I had a cold sore... I usually get them around that time every year. I had cleaning at the dentist office while i had a cold sore (but it was ending) and during that time,I also had an ulcer in my mouth... My boyfriend then develop a cold sore after mine was healing... somehow, the first week of January, my whole entire lips are burning, and the corners of my lips are cracked and I have itchiness and redness around my mouth. I tried abreva and it helps a little but if I don t have my lip balm or abreva, it gets irritating and uncomfortable.My face near my lips are also dry and itchy too.
