Hi again,
He still has a purpuric rash that breaks out every week--hundreds of little welts all over his body. He'll always have a few on his legs (where the vasculitis was) that get enlarged to about the size of a nickel. Just when we think they might continue to grow even larger (like the ones he had before that turned into vasculitis), they subside. Therefore, we think the run with vasculitis had ended.
When my husband went through those several awful weeks with severe vasculitis, he did have severe exhaustion and fatigue, just like you. He couldn't get enough sleep either, but he still continue to go to work everyday, because he had no alternative. He would tell me that he just didn't feel good in general. As the vasculitis has subsided, the fatigue has gradually gone away.
I'm hoping that your vasculitis will go away soon. It's good that you are trying to rest. Maybe the Prednison and Methotrexate will help you. My husband had a cortizone shot in his rear which was supposed to help with the vasculitis, but he didn't notice a difference.
Take care.
