Hugs and good wishes. Another friend was making an appointment to get a
physical and needed me to refer her to a doctor. I am sooooooo jealous of
you people who see your doctors less than 4x a year! (although, my doctor
is super hot, so it's not all bad.)
Feel better soon! It is good you made a doctor's appointment about the
"sloshing." No stress is a good thing!!
My mom suggested it might mitral valve prolapse--which upon light internet
research doesn't sound too scary. Neither does tachycardia.
Could be hyperactive thyroid. Very easily remedied and not life-threatening
or life-altering. Best wishes.
