While your feet are up

Liz, here is an easy exercise while you are sitting with your feet up. Flex your ankles (meaning pull your toes toward your body) hold that position then relax. Then reverse it, point your toes away from your body, hold it about 5 seconds then repeat. You just need to be careful not to hold the position too long or you might get a cramp in the foot.
Another good, yet simple exercise to strengthen the ankle and calf muscle is to pretend to write the alphabet with your toes; one foot at a time,
once each day, go through each letter of the alphabet.
That should give you a start.
As far as the stress, deep breathing exercises will do wonders. Inhale, while expanding the rib cage, then exhale trying to contract or make the rib cage smaller. Think good thoughts while doing your breathing. Do it daily, you’ll be pleasantly surprised.
Take care,
