Acupuncture insert needles to regulate your body to release certain neurotransmitters (i.e, endorphins) for your pain (headache, arthritis, fibromyalagia, dysmenorrhea....) or physiological problems (insomnia, anxiety, poor digestion, menopause, PMS...).
I am not sure what kind of acupressure mat you have, so I could not comment on it. My suggestion is to find an acupuncturist to evaluate what caused your back pain. You can bring your acupressure mat to the clinic and ask if it is safe and effective.
