Hello Dr. I Have Hand Lower Leg And Feet Swelling,

hello dr. I have hand lower leg and feet swelling, made worse by exertion. I have intense right leg pain from the top to the bottom of my foot, made worse when I lay down. I get easily short of breath, winded and am constantly dizzy and light headed. I have gone to dr's and blood test come back normal and they want to put me on antidepressants. I'm at my wits end. any advice you can give would be most appreciated.
