Hi Again - I enjoyed reading your post too, as well as many of the others. I've only been on this site for a week now and it's been super informative. There's also a lot of comfort in knowing you're not alone in this battle with the MonSter. Let's see if I remember this correctly. The hypothalmus lies near the base/rear/primitive part of the brain. This area controls the involuntary reflexes - the things your body does automatically like breathing, heartbeat and in my case, regulating body temp. Here's a funny - I had my gall bladder removed a few years ago. They wouldn't release me because I kept running a temp of 100 - 101 at night. They were concerned with infection etc. I kept telling them this was normal for me and to contact my neuro. After the blood tests kept coming back normal, they finally called him and he confirmed what I had been saying. MS can be very unpredictable and ***arre in how and when it chooses to present. And, as you're learning (unfortunately), there are a lot of doctors and neuros who simply are not knowlegable about MS. I hope your friend's neuro will be the right one. If not, don't give up. Don't you just hate all the hoops the insurance companies force you to jump through? If you don't mind me asking, in what area of the country do you live? Take care and keep your chin up!:)
