hi there

I have lupus too - and I think your rheumie is correct, the prednisone wouldn't be causing the muscle to shrink as it would be shrinking over you whole body if prednisone was the cause. Also, prednisone myopathy is easily treated with exercise, and you would not expect it to happen on a dose of only 6mg.

I have sensory motor neuropathy, so I have extensive nerve damage from my lupus which is giving me weak muscles in some parts of my body as my muscles don't get the signals that they need to move. But, there is nothing actually wrong with the muscles, they are normal, just not receiving neural input.

I would be thinking that it may be something other than lupus that is affecting your muscles, as I have never heard of lupus causing atrophy. When are you seeing your neurologist again?

cheers
