Hi, I am a 25-year old male. Two days ago when I woke up in the morning, I noticed a couple of bumps on my upper lip, one on the left side the other on the right. They started pretty small with a dry, crusted top. I didn't pay much attention to it and I thought it was because of the mango I had the night before. Then more rash appeared on both top and bottom lips and around my mouth. It's itchy and they all have dry, crusted surfaces and some have clear, yellow-ish discharge. Is this caused by mango allergy or is this herpes? I haven't had any sexual activities for the past month. Thanks ...
