I have ms and treatment is rebif. i have been experiencing flash like headaches. especially when i'm up walking. they. quickly peak, very painful?

Unusual: I wonder if these are a form of lhermitte's phenomena (a zinging electrical sensation usually radiating down the neck, but may travel upwards to the back of the head brought on by neck movement, usually flexing). Do you have a history of cervical cord lesions from the ms?

?Rebif side effect: Pts with MS have experienced headaches at 2-4X incidence of normal migraine sufferers. I have seen headaches exacerbated by all interferons, and often see relief when an oral med is started. However, headaches can be managed easily with OTC preps such as butterbur, feverfew, Co-Q10, riboflavin. Your neurologist can easily assist you.
