Hello, I have had this for over a month, I have tried every home remedy I came across and nothing helps

In order for us not to give you remedies you have already tried, please tell us what you have done so far.

So far I have tried Tea Tree oil, Neosporine, anti fungal creams, vitamin B complex orally and on the sores, canker sore cream, Blistex, plain face creams. Sometimes the sores will begin to heal, but next morning they are back or if I open my mouth to eat or drink they split back open.

Have you been to the doctor to determine what is causing them? That should be your first choice.

You DO need to see a doctor for your history, an exam, and testing for both Candida (yeast, a fungus) and bacteria, especially since it recurs every morning. Your own saliva, dentures, no teeth, medications, eating habits, and of course just natural folds can all be factors. If you need antibiotics and not just anti-fungals, you must get them from a doctor.
