hello. I'm a Physical therapist Assistant and when I was treating my patients, if something increased there pain, I would stop that procedure. You also have the right to refuse any treatment. You might want to consider a chiropractor. I to have thoracic pain with low back pain and a chiropractor has helped me more. Chiro's can do the ultrasound and electic stimulation with hot packs. I never did do low back traction on anyone with thoracic pain. But that the PT's decession and or the doctors.
