Fever blisters have no cure as of 2015; doctors recommend patients medication or remedies for the symptoms associated with the condition. Some of the remedies involved in managing this condition include ointments, antiviral medication and vitamin C supplements. Fever blisters are caused by the herpes simplex virus, according to the National Institute of Dental and Craniofacial Research.
Some of the symptoms associated with fever blisters include swelling of the lymph nodes situated in the neck, development of fever, painful or sore throat, painful sensations when eating because of sores in the mouth and difficulty in sleeping.
To manage pain when eating, doctors advise patients to consume soft meals in order to avoid irritating sore areas in the mouth. Since this condition is contagious, patients are advised to refrain from kissing others and avoid coming into contact with others since this may cause the virus to spread. Observing general body hygiene is key to preventing further bacterial infections that may take advantage of the situation.
Fever blisters will generally disappear after a given period of time but may return after a while, as noted by WebMD. Some of the things that may cause a return of this condition include fatigue, exposing the lips to the sun, pregnancy and allergies.
