Hi, I go to the Diamond Headache Clinic and they have been wonderful!! Noone else has even known where to begin with me until I got there. I am in the process of trying to find a medication combination to help with my headaches (they are clusters and I have migraines). It is a long first visit, and alot of questions at first, but they really look at causes, and what is best for you. So, I have made several trips there over the last few months, but well worth it. Do your research and know what you want to ask. Just my opinion, hope this helps, any other questions, ask away!!
