Texas Tech is definitely the top pain program with Raj and Racz on board. Our program, however, took Leland Lou from Tech (he was #3 behind Raj and Racz) and are set to hire away more of the Tech faculty. Raj and Racz are set to retire soon as well.
The implantable pumps are certainly the high end in pain procedures at this time but be aware that neurosurgeons are becoming increasingly competitive in this field in an effort to expand their role in chronic pain management.
The money is still very good in the field, but as with all good things, the specter of medicare crack downs are looming.
Failing to prepare is preparing to fail.
