K.P.
Texas Neurology which is located in the Lakewood area in it's own building on Gaston Ave. The Doctor I use is Dr. Steven Herzog. My annual hospital visits for Migrain relief is down from 6+/- emergency room visits/yrly to "0" hospital visit to date this year. I am attaching their web link.
Once on their site, go into the "Headache Center" for more information. Dr Herzog is wonderful. To my knowledge, he has been listed on the "Best Doctor" in Big D Magazine every year for the past 7-10 years.
