What do you think is the best treatment for bad back condition. Acupuncture, physiotherapy. Pt?

Combination. Acupuncture can relieve pain and spasm faster than pt, but pt will help with functional recovery.
Therapy. I believe that after making a diagnosis a physical therapist is best versed to help both alleviate the symptoms which usuallly involve pain and spasm. However, i believe it is just as important to work on increasing flexibility and core strength to prevent reinjury to the affected area.
