6. Fluid-filled Blisters: The Distinctive Progression
Often, the initial bumps evolve into a notable and concerning symptom: fluid-filled blisters. These blisters primarily grace the lips, but they can also venture near the nose or on the cheeks. Their presence not only amplifies the discomfort but also becomes an aesthetic concern.
The science behind these blisters is fascinating. The herpes simplex virus causes the skin cells to fill up with a clear fluid. This fluid is an accumulation of viral particles, white blood cells, and other cellular debris. While they look concerning, they’re actually pockets of the body’s defense mechanism at work.
For many children, the presence of these blisters becomes a topic of curiosity. Unlike regular bumps, these blisters are tender to touch and can often cause a slight stinging sensation. Their transparent nature offers a window into the liquid inside, often leading to inquiries and wonder. (6)
