Even though it is impossible to diagnose from the boards, I would still rather have someone tell me "well, its one of these 12 different things that cause that, and its most likely this one, and these 3 could be fatal, if this happens, you need to see a doctor immediately", etc. Than just be thinking to myself "well, this could be something serious, but I think I'll wait a day or too to see if it keeps up before going to the doctor." At least with the board, I'd have some sort of idea what would be killing me if I just keeled over, which I think would be better than not knowing anything.
