I’ve been experiencing sciatica this year and finally went to therapy. My therapist, who is great, introduced me to the tens 7000. He suggested I buy one and so I did. It’s a great device. It really does help stimulate the muscles and brings you relaxation and help in helping you with the pain from sciatica. It’s very easy to use too! Not sure what they can do to make it better. As the saying goes, try it you’ll like it!
