After walking in the woods, so very uneven ground, for best part of the day I found by the end my feet were starting to pain badly. Got home and discovered it was actually my ankles that had ballonned. Had to take painkillers and go to bed. Fine by morning. Now it’s happened again after standing and not managing to sit down all day. Has anyone any experience of this? Worried because the pain was so bad. Trying to drink lots of water regularly from now on but is there anything else I should be doing?
