A nice foot soak followed by a massage with oils. Then pile up a few pillows underneath your feet while you sleep (or whenever) to elevate them. That way the blood drains back up to your heart.
Im a stay at home mom n my left foot did the same thing but mine would crack n it hurts to even walk i just messaged mine with some bb lotion n it helpe me!
A nice foot soak or foot rub helps, I'm on my feet a lot at my job as well and my feet ache so when I come home my husband will rub my feet for me and I'll put them in a foot soak solution
