I agree with Nanners on this one. You do apppear to have Health Anxiety and the best treatment for this is therapy.
You differ a bit form most people with Health Anxiety as they usually frequent their physician's office as they are convinced they have a dreaded disorder and you don't want to know. You do however have the sx and worry about what you don't want to know. :)
Please do follow up with your Doctor as it is better to know then to be in a constant state of anxiety.
