I know this is a strange question..But...I need to know why i have fluid retention in my knuckles. i am on blood pressure meds, and i only get it when i'm drinking alchohol (wine) Reflexology calls this the heart region, is this because of a heart condition? I am under a doctors care. Also my fingers swell sometime when I walk for more than a mile. I've also been put on a diuretic. I try to eat well but salt intake is impossible to measure as so many foods are not as it should be and yes i do read labels, what is the daily intake for someone like me (sodium wise)? Thank you for your time
