Wow, you certainly do have a lot going on.
I don't recall anyone here having much in the way of liver symptoms/treatment, so I'm afraid I'm not much help in that department. Mostly my liver has just been watched when taking medications like Cellcept...
Now swelling, especially what seems to be changes in the face, I'm more familiar with. Several of us have changes related to prednisone usage - and I'm sure you know how that can affect the adrenals. Many have been left with inactive adrenals, necessitating daily doses on 5-8 mg of prednisone or one of its relatives as a replacement.
It sounds as though you need the help of a good endocrinologist - one who is familiar with systemic issues like Lupus - who can work in conjunction with your rheumatologist to get you balanced hormonally.
Sorry you are experiencing such difficulty, let us know how we can help.
