Sorry...shouldn't laugh at someones misfortune...but, ya gotta admit...a little humor never hurt anyone!
I don't think it's gonna subside till you actually have someone listen to your breathing with a stethoscope. This is where you can find out whether or not...you have some blood rushing back into the valve...which is where it came from (leaky valve)...or something other this serious.
Do you have symptoms of sweating...anxiety....obviously breathing difficulties...bouts of nausea....these are all symptoms of something serious sweetie....symptoms of a possible heart attack...
I do believe it's something you SHOULDN'T ignore though. Even if it does go away....the problem may still be there...and perhaps get worse.
