Cold Sore From HSV-1: Herpes simplex virus type 1 (HSV-1) is the cause of cold sores. HSV sets up shop in your ganglion neurons and reactivates during times of stress or when your immune system takes a hit. Pain, burning, tingling, and itching often proceed outbreaks which last around 5 days. Herpes is one of the most common infections with around 90% of people worldwide effected. This is not an allergy reaction.

If you are not describing cold sores you could be referring to canker sores. They are painful oral lesions that look like shallow, round ulcers. There are many reason why canker sores appear including family history, trauma, hormones, food or drug hypersensitivity, and increased stress. Treat with triamcinolone acetonide in Orabase, fluocinonide gel covered by Orabase, and topical analgesics.

Orajel: If it makes you feel better, that's fine. It does not speed healing, it only relieves discomfort for a short time.
