KN broda,

thank you for the pic... tara bro le aadhi kaam matrai garyau.. you did not mention what other tx regimen you had tried before.

By the way.. tyo cold sore or fever blister hoina... that looks like canker sore.

Uni le vaneko thikai ho.. lysine is over the counter product .. that you can find in any pharmacy... that is used for cold sore..

Broda, how often you do change your tooth brush?? and what kind of tooth paste are you using??? maybe it has SLS ( sodium lauryl sulfate). SLS gives foam when you brush the teeth. Squigle is a tooth paste with least amount of dermal irritants and does not contain SLS. Or ask the druggist in the pharmacy to hand you a tooth paste without SLS.

For canker sore: use over the counter canker medication.. use the one with benzocaine that will decrease the pain. Benzocaine is local anesthetic agent and will numb the area... decrease the pain.

Bottom line: Change your tooth brush and tooth paste. If possible use the toothpaste without SLS. You can add on once a day centrum (multi-vitamin). By the way canker sore is not contagious so you can are ok to kiss... hehehehe... Aba pani complication vayo vane.. see a dentist. Get well soon broda.
