Instagram star Deelishis posted a video, about her new "nose herpes" sore.

Deelishis told a story about how - for the last few years - she's been getting cold sores on her nose. And Deelishis explained that her grandmother told her that the nose sore is a result of the herpes virus.

Deelishis then asked her fans whether it is true, that cold sores are "herpes."

MTO News did some digging and can confirm - yes, it IS TRUE.

According to multiple medical websites, cold sores are small blisters that develop on the lips or around the mouth. They're caused by the herpes simplex virus and usually clear up without treatment within 7 to 10 days.
