I had an ablation procedure about 8 years ago on left side of neck that involved cauterizing the nerve in my neck. After over 45 years of almost daily migraines they were finally totally gone! I rarely even get a mild headache anymore. A friend had the same procedure done by a different doctor but it had no effect. Her migraines continue. I had the migraines caused by a horse riding accident at age 11. Perhaps the ablation only works on certain types of causes? Best wishes for you!
I did have a stroke last year (9/2024) but managed to survive it to the surprise of the hospital neurologist. It was a Basilar artery stroke 100% occlusion (Google it). Less than 15% survive. It was caused from irregular heartbeats from a head injury 10 years prior which has caused tiny clots to travel to my brain. Recovering hasn't been easy. My balance is bad but I refuse to use a cane. 8 months of symptoms leading up to the big one probably caused my brain to set up auxiliary routes of circulation that kicked in. Not having migraines made it far more tolerable. It was quite fascinating to study up on it using UTube videos.
My son lives in the east bay too. Fremont. Nice and cool place to live.
