My only suggestion is to use the search function on this site. This particular road (indeed this particular conversation) has been traveled hundreds of times, over and over again, by people with the exact same symptoms as yours. It has never turned out to be anything. Ever. Not even once. And that's not just me saying that, it has been said, and re-said, and debunked, and torn apart many times by people a lot smarter and a lot more well researched than me.
