Sorry to hear about your plight. Prayers up!
PS - You should definitely lay in a supply of Castor Oil and rub it into your legs from knee down - I’d bet after a few thorough treatments you would lose most if not all swelling.
Let it stay on for well after the oil is dry and wash it off with epsom salts. If the swelling is advanced remember to do this three or four times before expecting results. Stay off your feet for awhile too.
Best!
2ndDivisionVet - I will pray for you and your wife.
And I have used castor oil for a number of problems - it’s really potent stuff - try it!! It can do no harm whatsoever, only costs a few bucks, and may very well help materially. It’s very sticky, so I’d advise using old pants you don’t care about during treatment, or getting old towels to use between your legs and furniture. It cured very bad wrists with about 2 applications, years ago.
