Thanks Rita for the new thread and the name of those salts, I am going to try them as I can't stand this, it is making my legs feel weak.
Rosie, no it is not my shoes, I haven't been able to wear heels for a couple of years because of arthritis in my feet, at home I have a good quality slippers that have good support and are very comfortable, when I go shopping or whatever I wear comfortable hikers or runners, winter it is boots, no more fancy dress up places for me anymore.
