Still in pain 3 months help

[cinherenow]

Hi, my daughter Tara 17yrs old had spinal fusion and thoracoplasty on Jan 12,2005 ( 8 vert fusesd and 3 lower ribs removed). Two weeks latter her incision was oozing brown stuff. Back to surgery they opened her up cleaned out the incision and all her hardware. The infection was a gamma strep that cultural grew Enterococcus Faecalis. That got into the bone because of the hardware being infected.She is on a 12 week course of antibotics which has made everything worse. Her pain has never improved and we are seeing a pain specalist.
She is on so many meds and feels lifeless, has anyone got any suggestion are pain meds that have helped?
