I wear compression 15-20 mm Hg (Jobst or Medi) knee high stockings, and I sleep with them on (because I have no one to remove them at night). In the morning, my feet are still swollen (even with my feet elevated above my heart). If I am able to sleep without the stockings, my feet are completely drained in the morning.
I think the stocking compression in the calves is preventing the feet from draining.
Would it work for me to wear ankle high compression stockings instead of knee-high? That would also make it more possible to wear shorts.
