I am an aircraft mechanic. So needless to say the job has put a lot of strain on my back over the years. I would just like to say that I have had back pain issues for the last 10 years and my neurostimulator has helped increase my productivity and decrease my back pain tremendously in the past year, I leave it off until I am experiencing any back pain at all, it does a tremendous job of taking away the back pain and making me feel like a new person again, I don’t know what I would do without it, and I’m not sure how I got along without it for all the time I didn’t have it prior! I suggest you get the temporary one and try it yourself, it’s tremendous! You won’t be sorry!
