Dental procedures
When reactivated, the virus travels along the nerves to the skin, forming the well-known blisters. Although they usually appear around the lips, they can also show up on the chin, cheeks, nostrils, or even inside the mouth.
Recognizing the Symptoms
Cold sores usually follow a predictable cycle:
Tingling or itching – A burning or tingling sensation appears around the lips 1–2 days before blisters form.
Blisters – Small, fluid-filled bumps develop near the lip line or on the face.
Oozing and crusting – Blisters break open, leaving shallow sores that form a yellowish crust before healing.
The entire process usually lasts 7–10 days, and while the first outbreak may be the worst, future ones often become less severe.How to Treat Cold Sores
There’s currently no permanent cure for HSV-1, but several treatments can reduce discomfort and speed up healing.
Prescription Antivirals
Best taken at the first sign of symptoms, these medications can shorten outbreaks:
Acyclovir (Zovirax)
Valacyclovir (Valtrex)
Famciclovir (Famvir)
Over-the-Counter Remedies
For milder cases, drugstore treatments can help:
Docosanol 10% (Abreva) – works best if used early.
Lidocaine or benzocaine gels – relieve pain temporarily.
