My friend (middle aged female) just sent me a photo of her swollen feet, ankles, legs and asked for prayer. They have been this way for 6 weeks. She added that her hands are swollen too. She is a medical coder on required overtime -- 10 hour days including weekends. She wakes up with this swelling. One doc said it was the heat. Another salt retention. She functions by drinking Diet Coke. Doc told her to stop cokes and drink water. I told her that sitting most of your day is a killer. Increases your chances of heart disease by 45% ([per my Prevention Magazine) and just look at all the obesity among office workers who sit at a keyboard all day. She has some shortness of breath and just had a breathihg treatment today. She has what she says is a summer cold. She has no PC access at home. Your guidance, please.
