A patch of blisters at near corner of the mouth is caused by viral infections?

I am a women in my 20’s. 3 days ago, I felt an intense itchiness and redness near the corner of my mouth. Tried to recall and the only contact is my hand did scratched the area unknowingly once or twice. Then, I noticed that a patch of large and small blisters started to form at the same spot yesterday. No other locations were observed to have any blisters occurring. Currently, the pain is very minimal to only occasional pricky sensation. I had tried to found out similar conditions like cold sore but only tried some common remedies like cold compressions and applied econazine cream once then removed it after 30mins. It also felt a little better after using mouthrinse during the morning routine for a short while. May I know if this is most likely cold sore or other condition ?

If I would like to purchase proper ointment cream, which one will it be?
May I know if Herpecin L that says to help with cold sores are true ?
And may I know if there is any other preventive measures against recurrence of the blisters like disposing previous in-use toothbrush or daily application of lip balm (lemon balm - found online to have antiviral infection effects, but not exactly trsutworthy) ?

Hello and thank you for your question.

Based on your question, I understand that you are worried about your problem. I will try to help you.

You are having some blister-like lesions near your mouth corner with minimal pain sensation, hence you need some suggestions to relieve them. For your information, there are possibilities of them including cold sores as mentioned, however cold sores are predisposed for women of reproductive age via kisses or sharing of private items. They also may be caused by external irritation such as incidental biting of lips. Most accurate explanation and treatment option (most probable antiviral cream in your scenario) can be obtained from a doctor visit. Herpecin L does relieve the pain of sores, but it is uncertain to treat your lesions as we are not sure the exact type of lesion merely based on your description.

The main principle of preventing lesions in mouth area is to not irritate the mucosa either by food including acidic, hot or spicy foods, drinks or oral care products.

You should call your doctor or dentist if you have:

  • Unusually large or spreading sores.
  • Sores that last three weeks or longer.
  • Intolerable pain despite avoiding trigger foods and taking over-the-counter pain medication.
  • Difficulty drinking enough fluids.
  • A high fever with the appearance of the sore(s).

You can also contact our doctor online for further information and management.

I hope this answer helps you. Thank you.
