I have been having some strange bodily symptoms lately.?

I have had that fluttering sensation, too, and I think it is caused by gas. The itching could be caused by any number of things, including hemorrhoids or an allergy. Are you using a new soap? Have new underwear? I don't think either is anything to worry about, though if the itching continues you may want to see a doctor to get some relief. You are probably tired from the stress of worrying about it. We all have these silly symptoms from time to time and you're right, doctors tend to blame them on our emotional state or bad habits. (When in doubt, blame the patient.) A week from now you'll probably be wondering what you were worrying about. :)
