Patient :I have had a cold sore on the side of my lip for almost two weeks and have been trying l-lysine and icing it which haven't worked. Yesterday night I tried grapefruit seed extract from recommendations on the Internet. This morning I woke up and my cold sore was very painful and whitish (sort of like skin that has been in water for a long time) as well as some of the inside of my lip. Is there something wrong?
