Painful sores inside your mouth, including on your gums, tongue and roof of your mouth (palate). […] These symptoms may make it hard for you to eat or drink.

Small fluid-filled blisters often form along the border of the lips. Sometimes they appear around the nose or cheeks or inside the mouth. […] Oozing and crusting. The small blisters may merge and then burst. This can leave shallow open sores that ooze and crust over. […] Symptoms vary, depending on whether this is your first outbreak or a recurrence. The first time you have a cold sore, symptoms may not start for up to 20 days after you were first exposed to the virus. The sores can last several days. And the blisters can take 2 to 3 weeks to heal completely. If blisters return, they’ll often appear at the same spot each time and tend to be less severe than the first outbreak.

  Cold sores are highly contagious. The virus can spread through saliva, skin-to-skin contact, or touching an object handled by someone infected. […] Infection with the herpes simplex virus is life-long. While no cure exists, treatments are available to speed up healing and control outbreaks. Antiviral medications are available both as topical creams and oral pills. Examples include: acyclovir, valacyclovir, famciclovir, and penciclovir. In general, oral pills are more effective at treating cold sores than topical creams. Depending on the frequency and severity of the condition, oral medications can be taken episodically (at the first sign of an outbreak) or daily to suppress future breakouts. […] Cold sores seldom lead to complications. In most cases, cold sores resolve independently, even without treatment. There are certain circumstances where the infection can have more serious consequences and require prompt medical attention. Examples include: Infections near the eye. Herpes infections can spread to the eyes and cause HSV keratitis. Infections in babies under 6 months of age. Young babies do not have well-developed immune systems and can be susceptible to more serious infections. Infections in people with poorly controlled eczema. People who suffer from eczema can have tiny breaks and cracks in their skin. These tiny breaks and cracks can become easy entry points for the herpes simplex virus, thereby causing severe, widespread infections.

If you do get a flare-up, your primary care doctor can prescribe an antiviral medication that can lessen the severity and duration of your cold sore symptoms. These medications are most effective when they are taken within 72 hours of when cold sore symptoms begin.
