I hope you are ok with me crashing your board. I just wanted to try and help. MS and lupus have lots in common. They are both autoimmune and have many similar symptoms. Both can cause white matter lesions. Obviously, I am more familiar with MS. As most of you probably already know, once you have been diagnosed with an autoimmune disease, you may well be diagnosed with another. There is strong evidence for an over-all predisposition for autoimmune diseases.
IV solumedrol / steroids seems to be popular and somewhat effective in both diseases. In MS, it is more to help with symptoms than to treat anything. For MSers, once you start to flare, the overall damage has alreay happened. The steroids won't lessen any potential permanent damage or disability. It just helps you to get over that acute stage of inflammation/discomfort.
Obviously, anything that damages the CNS is scary stuff. Feel better everyone!
