Diagnosed in 2001 after a domestic episode caused a concussion and an MRI was ordered. Never had any symptooms that I was aware of . Took injections for 1 yr , had all of the symptoms of the flu for 5 days following the shot and could only tolerate a 1/2 can of ensure a day. Went from a size 10 to a size 2. Stopped the medication and was promptly " fired" by my neurologist as a patient and I have been continuing on since. I have symptoms, some painful, most not so bad, some stay for months, some a few days.
