This is driving me bananas. In the evenings (usually) my feet will suddenly get really sore and I look down to expect them to be the size of balloons but they aren't. They don't even look a little bit swollen, but there is pressure etc. like they are. This even happens on days I have barely even been on my feet. It's getting so bad it's keeping me awake and I have to put cooling cream on them, and a fan to try and ease it abit. What on earth is it? I have been heavier than I am now and recently so I don't think it's a sudden weight gain or anything. Thanks
