Hi Meid,
Being I'm in England I will answer.I understand what John is saying so give you a rough Idea of what to expect.You will probably have a physical examination and be sent for x rays and blood tests to start and then the rheumy will take it from there.
Nothing to worry about.Make sure you tell them everything you go through no matter how trivial it might seem to you.AS shows in many strange ways.
And welcome to KA by the way.
