The next day I developed a sore
throat , achy limbs, fever, and felt flu like. 3 days later I developed a blister
on my upper inner <span style = 'background-color: #dae8f4'>lip</span>
. I thought it may be herpes and bought acyclovir cream. It has now been 13 days, post exposure , my symptoms settled few days ago but the blister on my lip
persists. I have compared it with google images of herpes and it looks nothing like those. I am wondering if it is a mucocele.
