My trial was very good as well. It was the reason I decided to go with the implant. I have not had the implant as long as you, only three months, but have not found a program that works for me as of yet. My doctor has told me that it can take awhile before it will work but I am getting frustrated and impatient. I also need help from Nevro to find the program that works but I find support not all that supportive.
