It s been a week now after my lips became progressively very, very chapped. Now they re swollen, and so red it looks like I have lipstick on. They re itchy, mostly in the morning, and especially around my lips. The edges of my lips are even drier and more red. For the past 3 morning s I ve woken up with a yellow crust, either around my lips or even, this morning, gluing my lips together. I don t wear makeup. I take no medications. I don t have windows in my office and I don t go out into direct sunlight for long because I have pre-rosacea and I try to avoid flare ups as much as possible. I do not have eczema, and I have not been introduced to anything new that could be considered an allergen. I am not a lip licker nor a biter, but I do use lip balm. I d been using more and more recently because my lips were getting dryer and dryer. I also have zero cold sores. This has been afflicting me for a week now. What could it be and how could I fix it?
