What is a good way to cure cold sores and mouth ulcers?

Possibly: If it started off as a clear fluid vescicle first and occurs typically in the same place repeatedly, it could by herpes. If not it could be apthae. These - aphthous ulcers -are typically on the mucosa caused by your immune system that attacks your own mucosal tissue. Antiviral ointments for herpes and steroid ointment for apthous ulcers - both presription medications. Consult dentist /physician.

Best RX is TIME: The lesion undergoes a series of changes and heals over 14-21 days--after which the virus goes dormant. Anti-viral drugs based on Acyclovir are available by prescription and can be taken as a preventive med. Otc meds, like abreva, have variable success rates. If they occur frequently, can take Valtrex (valacyclovir) daily as a preventive measure, but will need a prescription. Warm salt water rinses can comfort.
