Herpes Simplex
"I got a cold sore yesterday morning, it was quite small and barely noticeable. I put abreva on and put it on like 10 times and when I woke up this morning it was bigger and more painful. It does not work. I don&#039;t get cold sores quite often, only when I&#039;m very sick or physically drained (I&#039;m a lifeguard and swim teacher). This was a huge disappointment, especially for how expensive it was."
