We don't have a list of doctor who perform this, I'm sorry to say. You'd have to do a bit of research on that.
I'd also like to mention if you've not seen a "true" migraine/headache disorder specialists, I would encourage you to do so. These doctors are different from neurologists in that they are board certified in headache medicine which is different than being certified in neurology. Neurologists may be fine doctors, but have a hard time being experts in one area because they treat so many different conditions such as multiple sclerosis, stroke, epilepsy, Parkinson's and others. Migraine/headache experts treat one condition all day, every day migraine and headache. Let me share this information with you on how these doctors are different and how to find one; https://migraine.com/blog/really-find-headache-specialist/
