I can't imagine how much pain you are enduring in order to take care of things.
Somewhere I missed the post where you told us you have an inherited neuropathy. I'm so sorry I missed it and didn't comment.
I suffer thru the yeast problems continously. Seems to be part of the territory of Sjogren's. And cutting back on sweets and lots of yogurt seem to be my best way of handling it too. I've used yogurt on both ends.
I hope your son improves and you start feeling better soon.
