Thanks everybody - at least I know it's normal for things to get randomly worse and better. If it persists I will definatley go see a doctor. Thanks No meds. When I was first diagnosed with MVP they gave me a beta-blocker - BAD IDEA! Yes, it diminished the symptoms - but one of the side effects was depression, and out of all the nicer side effects like "drowiness" and "slight tingling sensation" I got the worst one...DEPRESSION! It was terrible, and I began to feel better after being taken off of the beta-blocker. A couple of months ago I was on Paxil, but got taken off of that because of excessive weight gain. (Side effects SUCK don't they??) ANyhow, now I am on no medications at all. You think perhaps this is why I'm having such a hard time with my symptoms? You're right, the first day I had this worsened symptom I think I definatley hyperventilated myself. As far as anxiety goes, the only reason I think it isn't, is because I'll be sitting down, resting, calm, with nothing on my mind, and suddenly I can't breathe. UGH! Yeah, the virus thing could very well be it. My nose is a little stuffy, so my mom seems to think I have a slight chest cold - and according to one website I visited, the symptoms can worsen if you have a cold.
