What is the reason for granule like things at the corner of my lips?

Q: I am a 27 years old married woman. At the corner of my lips, there are some granules like things. Could you please suggest me what this is and the cause for it?

A:If the eruptions consist of tiny blisters in groups, then probably you have herpes labialis. This condition is recurrent. Acyclovir ointment should help in faster resolution. In case there is secondary bacterial infection, antibiotic may also be required.
