I’m 15, and recently shared lipstick with a friend who had a sore on the skin above her mouth, although I’m not certain it’s a cold sore (probably is). Days later, I noticed what looked like the start of a cold sore, yet it disappeared completely less than an hour later. Another similar sore began to appear on the other side of my mouth, and this one had three pimple-like dots inside of it. I’m unsure if any tingling or burning was psychosomatic or not, as I’ve been incredibly concerned over this and am prone to imagining symptoms. I decided to pop one of the three dots, and sebaceous filament came out. Now, that dot is slightly crusting over. This has been very frustrating, as each symptom that is common in herpes is immediately paired with another symptom that says otherwise.    It’s pretty small and hard to see on my skin, but it’d be frustrating to have an incurable and pesky virus. Thanks to you all for your help!
