GreyGoose, I can't tell you how much I've been through this. It's an example of how the internet can be your enemy. First, I thought I had colon cancer after hours of reading about it on line. I went through many tests and nothing was found. Something else, which I mentioned a while back, happened last year. This is how anxiety takes it's toll. I would start to get this on and off sensation of a slight weakness in an arm, leg, or both at once. The more I worried about it and glued myself to the internet, I thought I had a brain tumor or strokes. One day in a panic, I went to the ER. After about 3000 dollars worth of scans and other tests, they couldn't find a thing. I was only diagnosed with anxiety. All that worry and $$$ to tell me something I already knew. If it's not one thing, it's something else. I've finally learned to stay away from reading about disease symptoms on the internet.
