Thanks, Mat. It goes without saying that we share a number of symptoms, and I see this quite clearly looking at your list of symptoms. We do both have SFN, so that's likely it. I'm not sure if we have the same cause, but it's certainly possible. I'll keep looking and perhaps at some point I will have a lip biopsy. Like I said, at some point I will see another rheumatologist. Unfortunately I'm too busy for that these days. Perhaps in the new year.
