Cold sores, also known as fever blisters, are tiny, blister-like lesions that appear on the lips, chin, cheeks, or nostrils, as well as the gums or roof of the mouth. They are caused by a herpes simplex virus infection. Antiviral drugs may aid in their management.
Symptoms of cold sores:
Depending on whether this is your first outbreak or a recurrence, your symptoms will differ. Symptoms of a cold sore may not appear for up to 20 days after being exposed to the virus for the first time. The sores might continue for a few days. And it might take 2 to 3 weeks for the blisters to heal fully. If blisters reappear, they will frequently develop in the same location and will be less severe than the original outbreak.
You may encounter:
- Headache
- Fever
- Gums that hurt
- Throat ache
- Headache
- Muscle pain
- Lymph nodes that are swollen
Cold Sores Causes:
Close contact, such as kissing, spreads cold sores from person to person. Herpes simplex virus type 1 (HSV-1) and, less often, herpes simplex virus type 2 (HSV-2) cause them. Both of these viruses can harm the mouth or genitals and are transmitted through oral sex. Even if you don’t notice the sores, the infection can spread.
Treatments:
You can apply lotions or ointments straight to the sore. If you start using these lotions as soon as you sense tingling or itching — before the cold sore appears — you may be able to avoid it.
Your clinician may prescribe an antiviral medication that you use orally to treat cold sores.
Preventions:
Take the following precautions to avoid transmitting cold sores to others:
- Keep your hands clean at all times. When you have a cold sore, wash your hands well before touching yourself or others, particularly newborns.
- While blisters are present, avoid kissing and skin contact with others. When blisters release fluid, the virus spreads most quickly.
- Items should not be shared. When blisters are present, utensils, towels, lip balm, and other personal things might transmit the infection.
