You sounds just like me too. When I was 18 year old, 10 years ago, I went through a string of tests trying to figure out what was causing my chronic n*. No one could give me an answer and I was so convinced that I had some horrible disease like cancer, etc. I went to my regular md, then a gastro doc, then a nuerologist and had all of those tests just to come to the conclusion that my n* comes from ANXIETY.I totally agree with what ameize has to say up top to you. I feel for you because I am scared every day during the winter that I, my husband, or my daughter are going to catch a sv*.
Welcome to this site, this is a great place to come for support! I'm new too and I've been able to deal with my fear a whole lot better knowing that I'm not the only one who feels like this.
