Hi, just wondering if anyone has ever used a TENS unit. The PT suggested that I get a script for one from my OSS. I had a 2 level ACDF on 12/9/2010. I still get major neck and shoulder pain, knots and spasms. I have been on the computer alot of work. I am a teacher and tend to look down quite a bit or turn very quickly. My ROM has increased, but my strength is still quite poor. I use the cervical stim 4 hours a day. I went back to work on 2/14/2011 and started PT on 2/21/2011. I still have some swallowing issues, not major. Has anyone used the TENS for pain? How did is work? Was it worth it? Thanks for your responses.
