Oh My Obama! There are literally hundreds of ailments that can cause those symptoms, not the least of which could be weight, inactivity, low sodium, poor diet, or drug interractions. It also could be as simple as sleeping incorrectly. I couldn't believe the OP when asked if they had been worked up for a cardio they said not that they knew. Uhhhhh, yeah. They are a bizarre bunch though, aren't they? DU would be the LAST place I would go for medical help.
