Herpes simplex 1: The most common cause of canker sores in the upper respiratory tract is the herpes simplex virus. Unfortunately, the virus is in the nerve and migrates to the skin or mucous membrane under stress such as a menstrual period. There is not much you can do. But the use of xylocaine (lidocaine) viscous, a topical anesthetic as a gargle may alleviate the pain.

Canker sores are not caused by a virus. Herpetic lesions or sores are possible from the virus.

Canker sores?: First, who made the diagnosis of canker sores, also known as aphthous ulcers? True canker sores are of unknown etiology but thought to be an autoimmune response, triggered by stress. She may have that or herpes simplex 1 virus (or both). Both are painful ; need to run their course. Halls may help or be further irritating to the mucous membranes. Consult with dr. Regarding diagnosis and treatment.

I think that Halls would really irritate the ulcers. See your dentist or an ENT specialist for diagnosis and relief of pain recommendations. In any event, they should run their course in 7-10 days.
