I've noticed that since turning 40 a few years ago my lower legs are starting to feel really heavy by lunchtime and by the end of the day I have swollen ankles. Not excessively so, but to the extent that I have to put my feet up in the evenings.
I am slightly overweight and do have issues with varicose veins (although got the worst ones treated a few years ago), plus my job is sedentary at the moment. I try to get out for a fast walk at lunchtime which definitely helps but is there anything eIse can do to reduce the heaviness? Drink more water? Morning walk before work?
I wish I had a more active role but sometimes it can be so busy that I don't move from my desk for a couple of hours because of all the demands coming in.
