I have had symptoms of MS for over 10 years now. They include tingling, numbness, balance and coordination problems, blurry/worsening vision, memory & concentration problems, severe fatigue, severe muscle cramps, sciatica, overactive bladder & leakage, dizziness/vertigo, & muscle spasms. All of my MRI's have been negative along with my LP. The only thing that was positive was my ANA and the LP showed "rare mononuclear monocytes". Rheumatologist ruled out lupus & other autoimmune disorders. Neurologist didn't diagnosis MS, but wants to do yearly MRI's because of my clinical presentation. Could you have MS even though MRI's and LP is negative? Also, on a side note, my mother & great aunt both have MS.
