Relief for back pain?

Agree w Dr. Ibrahim. If you have chronic back pain - it is important that it be worked up. Since you are receiving physical therapy - suspect that was already done. Acupuncture can be very beneficial for a number of types of back pain. It can reduce pain ; inflammation and improve range of motion, blood circulation, lymphatic drainage and nerve conduction.
Stretching. Strengthen abdominal and back muscles, hydrate frequently.
