I find your post very interesting with some similar themes to health issues I’ve struggled with. There may be no connection, but I wonder if simple vitamin deficiencies have caused some of your symptoms. I was diagnosed with rheumatoid arthritis 40 years ago, migraines 30 years ago, and c diff just two years ago. I have struggled with high cholesterol and at the age of 40 developed FOOD allergies! Over the past two years I have become a probiotic evangelist, believing they are the secret solution to many of the worlds health problems! I have recently been feeling extreme fatigue (similar to the way I felt just before getting sick with c diff) and have also started having migraines again (for which I am no longer on medication and have been gone for years). After running some tests, my doctor discovered that I have a deficient level of vitamin D (at 13) and an insufficient level of B12 (at 270). I am currently taking a prescription dose of D along with a B50 complex and additional B12. The migraines are gone and fatigue is getting better. You will find interesting research by Dr. Holick online supporting the vitamin D deficiencies causing many health issues. Additionally, I found Dr. Gominak’s work to be fascinating. She explains how, with the proper levels of D and B vitamins, our bodies supply sufficient gut flora. In any case, I’ve read there could be a connection between vitamin D levels and sjogren’s symptoms you describe. Wouldn’t it be wonderful if it all turned out to be solved with vitamins! I wish you the best of luck!
