remeber that this is a hunt for clues for what is wrong. Rarey does any one test become a Eureka moment (if life were only that easy, eh?). MS is a process of elimination, experience and supporting observations and tests. In fact, many people go into the testing phase/limbo land and actually end up with a diagnosis of somehting else all-together.
Worrying won't help, won't make an answer appear faster - it only causes stress and anxiety.
Sometimes waiting and wondering is the hardest part. Know we are here to answer any questions (heck, we have ALL been where you are at now). We are a good group of folks, albeit somehwat strange & goofy at times, who care for each other, can put medical-esse in simpler language and provide tips along the way.
Regardless of your eventual diagnosis, welcome!
