super advice betsy.
i cannot wear anything with elastic on my legs. it hurts so badly. i use all cotton socks and in the winter fleece socks for warmth and they have no elastic.
also epson salts in the bath are the best . i get some with lavender in them and they are sooo relaxing and do help with the swelling.
the eversion might require a brace to protect the ankle from weakening. that needs a good physical therapy doctor to advise.
and i put my feet up and down so much in one day and i try to keep my feet moving whan i am sitting.
the breathing could be a side effect of fluid build up from meds and needs to be addressed quickly ....

Get to an RSD specialist and get a block. If this is done early the chances of success are high. If you wait more than two years it tends to become intractible.
