Dear Mary,
My apologies. I have not been notified of your questions above and just happened to stumble upon it today by accident. I am glad to hear from you.
You mentioned that you showed autoimmunity to smooth muscle, known as anti-smooth muscle antibody, or ASMA for brevity. This antibody is seen in autoimmune liver conditions, but is also seen in overlap in and with other autoimmune conditions, so in my opinion the relapsing polychondritis is not ruled out, since it overlaps with many autoimmune conditions. This, along with you elevated Rheumatoid Factor (a rather non-specific marker of autoimmunity) both make me clearly concerned that you have an underlying autoimmune disorder, and I still wish for you to have a thorough Rheumatologist evaluation.
The RF of 1:640 means that your blood needs to be diluted 640 times in order to have the Rheumatoid Factor autoantibody become undetectable. The fluid in your legs could be from many different conditions, but with normal liver function studies, liver failure is not likely. You may have some problems with the valves in the deep veins of the legs, called venous insufficiency. I would also wish to make sure your heart is pumping well and that the swelling is not due to congestive heart failure -- an echocardiogram should answer that question. We generally treat venous insufficiency with a diuretic ("water pill"), leg elevation while at rest above the level of the heart, and sometimes compression stockings to help provide support and prevent reaccumulation of the fluid/swelling.
I have another idea if you wish to try to contact me in the future, and that is you can go to my profile and specifically request me from there if you wish. I believe that will generate an email to me notifying me that you have a question. If I don't answer it in a fraction of an hour, it becomes available to other experts to answer, but you can always write "For Daniel Nelson, MD only:" or something similar. Remember, I do not get online too often so I may take a day or so to respond, but I will respond as soon as I can once notified.
I hope this helps, my dear. Keep me appraised of that Rheumatology appointment with Mr. Creamer at Southmead in Bristol. Cheers.
