Third time’s a charm, right? I had one neurologist for years whose mantra appeared to be ‘every headache is a migraine.’ Different hospital, new neurologist. During my ninety+ day headache gave me the same type of medication and said “come see me if it doesn’t improve we’ll put you back on a medication you’ve previously been on.” NOOOO!!!
Some headaches are shunt-related and have more to do with fluid dynamics than blood vessel dilation. Finally, maybe, a neurologist who gets it.
