Sore, swollen feet

ladyartichoke

I live in Singapore so it's very hot and humid. Ever since I moved here I've been getting sore, swollen feet after walking. I put this down to the heat and it would subside in an hour or so. But the last few days my feet have not stopped burning. Walking is uncomfortable, I'm tottering about like an old woman. I get a little relief from cold flannels, keep my legs raised at home but the pain and burning has spread up my legs to about my mid-calf. I am in touch with a doctor but I really need some advice on how I can get reduce the swelling and pain long enough to do some exercise.
