I have been having MS like symptoms that are progressing over this past year (pins and needles in my left hand, then right hand, right leg, left leg that come and go, cognitive fogginess, huge memory problems). My MRI showed no lesions thankfully and he did blood work, I thought to check for Lupus as well since I have joint pain that comes and goes as well but I'm wondering if MS detection can be shown through blood work by having elevated white blood cells?

Would you have to have an elevated white blood cell count in order to have MS with or without lesions showing up on an MRI?
