@tigreyes2004 I just got the DRG stimulator implanted in me about 3 months ago, and it is barely working at all. I would suggest to you that if you do the trial for the HF10, that you do the trial for the full 10 days, and that you should have mostly successful days during it. I had a 10 day trial, and pain lowered by about 50% only on days 7, 8, 9, and on the 10th day, it was removed in the morning. Also know that sometimes, there are successful trials, and still, it does not work. Leads can migrate, and the surgery itself is surgery! It is painful, and healing takes months. Many, many people do well with the HF10. Just know that there is risk, and no guarantee. My best to you. I have had electricity to the leads in my back several times, and it just does not help. My pain doc still thinks I should not give up. I go for another adjustment this Tuesday, but I am no longer hopeful. Also, there are stimulator blogs on the internet. Find these blogs, and read about real people, not the advertisements for the HF10. Advertisements try to sell you. Read real people, real situations. Lori Renee
