Just sharing what I have learned over 40 years of cankers.
I have had cankers since I was about 10. They progressively worsened until my 40’s. I had plenty of doctor / dentist visits including a referral to an ear nose throat specialist and an allergy test. No body could actually help or tell me what was wrong.
After a particularly bad breakout of cankers in my throat my wife dragged me to acupuncture. Although I can’t say the act of acupuncture itself helped having the therapist read me the riot act of having to take care of my self or risk getting throat cancer woke me up.
I was prescribed a candida diet. It was very strict and I followed it for six weeks. Not only did my cankers subside I also felt much better. Now when I can feel when it’s time to do a reset. I go on an elimination diet for a couple of weeks to reset the system and life improves.
When breakouts do happen I find that hot salt water helps the healing process and provides some relief. I try to stay away from topical pain meds as they seem to slow the healing process. At night after brushing I will have a spoon of Greek yogurt and then suck on a little bit of Manuka honey in an effort to balance the system.
I have family members who suffer from Chrons and as crazy as it sounds I feel canker out breaks are a similar response to gut imbalance and stress. In my case it just presents as cankers.
