My friend has a very swollen right foot and left hand. She has been to the doctor several times in the past two years with no results. They have checked thyroid function and given her edema pills; have also tried progesterone because the foot began swelling after she stopped using birth control shots five years ago. If you have any suggestions, we're open. She is maybe 10-15 pounds overweight and also stopped all dairy products two years ago for stomach upset. thank you.
