Heather Gloria began writing professionally in 1990. They can also be found inside the mouth, but this is less common. Herpes simplex 1 primarily causes blister-like sores on the mouth, lips and face, although these blisters can be caused by herpes simplex 2, the virus that usually causes genital herpes. Yes, fever blisters, or cold sores if you prefer, are the result of the herpes simplex 1 virus. Fever blisters, also called cold sores, usually occur outside the mouth — on the lips, chin, cheeks or nostrils. The spread of infection can still occur from someone who does not have a visible sore, but has the virus in his or her saliva. The blisters may be accompanied by fever, swollen neck glands, and general aches.
Even though you may have recovered from the initial outbreak, the virus remains dormant in your body until something triggers it. Orange juice is a common food trigger for fever blisters. Once recovery has occurred, oral herpes or fever blisters may recur in the form of fever blisters in some people in later years, while in others it lies dormant forever with no symptoms. Once a person is infected with oral herpes, the virus remains in a nerve located near the cheekbone. But often, it takes a slightly different route and ends up as a blister on your lips. Acidic foods feature pH between 0 and 7. The sores will slowly get better and those on the skin will crust over and heal.
But some common triggers appear to involve the immune system, such as physical and emotional stress. Hormonal changes also affect the immune system and may trigger an outbreak. This acid can produce subtle corrosions in the tissue of the mouth that set the stage for a fever blister outbreak. Fever blisters are small groups of blisters on the lips that are caused by reactivation of herpes virus in an individual who had primary infection as a child. The sooner you treat a fever blister, the easier it is to make sure it doesn’t stick around long. Take a natural supplement that can boost your immune system. On the other hand, foods like orange juice move freely, actually bathing the surrounding tissue and prolonging contact with the damaging acids.
If the sore is caught very early, during the stage when the only symptom is the tingling sensation at the lip margin, then an antiviral ointment called acyclovir may be effective in preventing a full cold sore from developing. Resist the urge to scratch, pop or pick at the blister or scab. Irritating your skin will only prolong the healing process. Although some people report that drinking orange juice triggers fever blisters, the National Library of Medicine lists no studies that confirm this. If the cold sores are extensive and are preventing you or your child from eating and drinking normally, you should see your doctor. They are extremely contagious. While you’re experiencing an outbreak you can infect someone just by kissing them.
MedlinePlus does, however, recommend abstaining from orange juice and other citrus fruits once an outbreak occurs. That includes oral sex. Although the HSV-1 virus is generally responsible for fever blisters, it can cause genital herpes. Probably not, although most people find that outbreaks happen less often as they get older. Although the ointments eventually wash away, they provide a temporary protective barrier between mouth tissue and acids. That’s because the virus is almost impossible to eradicate. Once you’ve contracted it, it never leaves your body completely.
Even with prescription medication, the best you can hope for is a reduction in the severity and frequency of flare-ups. But some people have been able to control their symptoms, and even eliminate the virus with the use of natural methods and supplements. Fever blisters on the lip are the worst because they are so visible. You can’t hide them with make-up or clothing and they take ages to disappear. But you don’t have to live them forever. Do some research and you’ll find a safe and effective remedy that works.
