We wish we saw Dr. Han years ago. My wife had very bad migraine headaches and was treated by at least 2 neurologists and one pain management doctors before. She tried almost everything in the world for migraine without help. After she was referred to see Dr. Han, he first gave her some special injections and then put her on medications. Now her headaches have decreased by more than 90%. What a difference Dr. Han had made on her quality of life.
