I am wondering why my right arm randomly goes numb for no reason at all. I don't lift anything heavy or anything of that sort, so what could it possibly be? Some of my friends seem to think these are early signs of a possible stroke or a heart attack but I can't really buy that since I am 22 years old, fairly relaxed with a normal amount of a stress than any college student would have. I also take no medications, I live a fairly normal lifestyle.

Why do I get the dry heaves when I get hungry? I used to never had a problem getting hungry...if I couldn't eat for a little while. In the last couple of years I have an almost instantaneous reaction when I get hungry. All of a sudden I go into the dry heaves. I have to desperately search for something to eat or eat a Tums. It's rather annoying, not to mention uncomfortable. Other than that I don't have any symptoms. Does anyone have experience with this. Ideas? [more inside]

Many years ago someone told me the recognised term for the kind of involuntary shudder that commonly affects people at rest. You know the kind that spontaneously rocks you, just for a moment, like you are shaking off the ghoulies, like the cliche says 'someone was walking on your grave'? I have since lost this word to time, and searching the internet has brought only partial results. Does anyone know it?

VitaminFilter: I am a reasonably healthy male in my twenties, and I take a regular old Centrum multivitamin every day. My current huge container is almost empty, and before I buy another one, I'm wondering if there's something better. Is there really any difference between the various brands of multivitamins? Is there a brand better suited for someone my age? I have access to Whole Foods, Wild Oats, Trader Joes, etc., if that helps.
