good luck bob, i hope they can make a quick diagnosis one way or another, it will help you move forward. i was diagnosed last year after very similar symptoms to your own, my right quadriceps was cramped up and numb when i woke up one day and was like that for over 6 months. i am in remission now, i guess. the mri should be able to tell you if your doctors are on the right track. i have also had the incontinence problems during the first month of my attack, and i understand that it is not the easiest to deal with. glad youre here, this place helped me immensely, i learned way more about ms here than from my dr or anywhere else.
