If her symptoms are getting worse, I would definitely try to get her in right away. If you advise the dr's office of her status, can they somehow "squeeze" her in to see her? If not, then, I'd start to look for an "alternate" route. I know MM specialists are hard to find. (Trust me, I live on an island, and sometimes feel like my hands are tied when it comes to medical care).
I had my surgery done on the mainland in North Carolina and didn't return home until about 14 days post op. My neurologist followed me during my post-op period during those days. Upon my return home, I followed up with my neurologist within 2 days, and saw him 1 a week for a couple of weeks, then gradually it went to every 2 weeks, etc.... (I had a double by-pass and an in-direct surgery, so I'm not sure if that's why they followed me very closely. I also was pre-symptomatic before surgery. Thank God I haven't had any symptoms since.)
I also had MRI/MRA's within the year, and at 18 months post-op, I had an angiogram. I'm almost at my 2 year anniversary mark (March 27, 2007), and I've been advised by my "local" neurosurgeon that I should have either a SPECT or PET scan done (none of which I've had before

)
I think we've all had different follow-up depending not only on our doctors, but also depending on our symptoms.
I think that from what you explained above, she should definitely seek advice from her neurologist. I hope they can take her asap!

That's just my

. I hope your fiancee is able to get the medical attention she needs soon! She'll be in my thoughts and prayers...
