Hi Ali,
I'm sorry, I don't live in Scotland (I live in the U.S.A) - so I can't help you with any doctors, etc. Like Joe mentioned, one of our Staff Moderators lives in Scotland but she is away for a few days.
It is so frustrating, isn't it, when doctors don't "get it", don't listen or can't offer any help to the health issues that come up? I am fortunate that my doctors are all very helpful. For those who don't have the blood markers of Sjogren's, they have a difficult time finding doctors who will listen and treat them based on symptoms. (I have positive bloodwork.)
I'm sorry your husband is dealing with a lot right now - but, he is fortunate to have you doing research on the web on his behalf.
I hope you are able to find doctors that you are happy with and who treat your husband with respect and compassion - which he deserves.
Bucky
