Hi Desi,
Sorry that things are not travelling well for you.
I have massive oedema so I do sympathise with you, it does seem to create a different type of pain.
I try to where tubigrip (when I can talk myself into it) on my legs. Some days it is possible---some not. But it does help a little.
Whenever you sit down put your feet up and rest your arms on pillows.
Epsom salts do help, just as Joan says. If you can't get in and out of a bath if you can get someone to fill a big basin or bucket up for you, that will work also.
Hope you feel better soon
Love Tayla
