@gypsyblue: Way too many! I went to a Functional Medicine doctor about 12 years ago for treatment of an environmental mold allergy causing serious sinus issues requiring a surgery. Doing that really helped to solve my issues, however, it took about 2 plus years to finally get past all of that. I took out my old notes to review test results, recommendations etc. I have also been reading a book called Dirty Genes by Dr. Ben Lynch. If you google his name with OLP, an article pops up about his own experience having OLP. Lot's of good info in his book. Another good resource was typing "autoimmune disease treatment plan from a functional medicine point of view" in ChatGPT...the most helpful! The supplements are individualized in all those resources. Every resource talks a lot about AIP elimination diet and lifestyle changes...sleep and stress reduction. So far, I have made a lot of changes, but nothing 100%...yet...
I would like to go back to the Functional Medicine doctor, but it is rather costly and I'm retired now. So far I have private paid a periodontist and the oral med specialist at UCSF because my Healthplan does not cover them. There are so, so many supplement recommendations, but they are individualized to a person's needs depending on their test results. A few entry level recommendations are Vitamin D3 and K2, a methylated multivitamin, magnesium, Omega 3s, B complex, zinc, etc, etc, etc, etc. Check out the book Dirty Genes. That might be a good place to start. Let me know where your search leads you and what you find out at Washington University. 25 years...yikes. As per my previous post...Cleure toothpaste gives me a lot of relief. Also, avoiding anything that stings or burns my lips or mouth. Aquaphor to my lips 24/7. I'm still waiting for the Dexamethasone rinse to be filled by my pharmacy. Hope you get some relief soon. Take care.
