I saw my new neurologist yesterday and he gave me a prescription for Verapamil, a calcium channel blocker, to try while I am waiting for next MRI to see if there is evidence of active cerebral vasculitis. They have not treated me with prednisone in the past four months of this flare because they did not want to mask any vasculitis that could show up on tests. Would the channel blocker not dilate blood vessels in my brain and then also mask any vasculitis that may be lurking there? I am always hesitant to start a new drug so if any of you have some experience or knowledge to share, I will be very grateful. The headaches are becoming very frequent and painful and I am currently using percocets for relief.
