I am super paranoid about everything literally all of the time. My lips randomly got swollen last night and now I think I have herpes. I have comparing my lips to pictures on the internet, why? Good question... I know that it is never a good idea. It just got super cold here where I am from, and dry out. I am a college student so I do spend a lot of my time outside. My upper lip randomly gets swollen right in the middle and I think I stared at my face in a magnified mirror for longer than I ever have before. Lol. I have no blisters, just random cracks in my lip? I have been using blistex medicated lip ointment and I am also kinda wondering if the swelling could be a reaction from that. Thoughts? Do you think it's herpes if I do not have any sores?
