I need a chronic pain doctor in Chattanooga, TN?

Chronic pain from chest wall due to surgery to remove a 13cm tumor (sarcoma) from left chest wall. Removal of tumor also included removal of 4 left ribs, part of left lung, part of sternum, reconstruction of diaphragm, removal of 22cm of tissue and muscle from chest cavity and then Gore-Tex mesh was placed inside chest cavity and skin flaps glued over mesh. Alabama doctors feel I need no pain management and are upset because I filled a prescription for Lortab when I had oral surgery in 2/2011 because I had Percocet to take for chest wall and nerve damage pain.
