Hi I have low potassium levels I take pills for it I also have low active thyroid and take a pill for that as well my doctor told me that my levels are almost normal again but I'm having problems with my legs swelling and my feet I find that if I'm on my feet for more than 20mins my legs and feet are so swollen that its painful also I find that when I wake in the mornings my feet more my right foot is numb and to step down on it feels like its hard like its frozen I just want the swelling to stop so I can do my own shopping cleaning walking my dogs the everyday stuff that most people take for granted.
