The power of the mind over the body is incredible! Like you said about getting the twitches more often... As soon as I googled why I had a twitch in my arm and found the other symptoms, BAM I had those also. Within minutes and hours.
It's unreal. Because of that fact alone, that just proves it is not MS and is anxiety. My doctor told me during a flare up, which is when you have symptoms, the new symptoms and symptoms in general appear at the same time...not another one several weeks after the onset of the first symptom. They also don't come and go, and don't really jump around in location, because the lesion is stagnant on one location.
Even though we know all of this though, it is hard to not worry and awfulize. I think I am going to see a therapist because I really just cannot handle myself right now and everyone I talk to about this is getting so frustrated with me that they are fervently urging me to do the same. >_< I think I'm going to start exercising again, reading again, taking walks (hopefully the weather will permit)...just doing anything to take my mind off of all of this.
Also, last thing I'll say, but does anyone else seem to notice that "old" symptoms seem to "improve" when you start to focus on a new one?
