BANJOKATT,
I've found that a Migraine specialist is usually best for treating chronic Migraine. Neurologists aren't necessarily Migraine specialists, nor are pain management specialists. Pain management specialists often know very little about Migraine, especially Migraine prevention. There are several good Migraine specialists in the Chicago area.
