Not a bad thought but PMR is not usually confined to the feet and doesn't have a lot of edema

Peripheral edema without dyspnea on exertion---not likely and also not painful

Exercise the instep of your feet by placing a cold water bottle on the floor and roll your foot over it.
Stand on a step with your toes and stretch your Achilles’ tendon.
Take anti inflammatory pill if you can.

Plantar fasciitis in BOTH feet at the same time and again with edema---unlikely
