Hello Angelina!
I am so sorry to read of the way in which your trial is progressing. You need to be putting all of the thoughts you expressed here into your pain diary the Doc most assuredly gave to you on which to keep notes during the trial.
If it is appearing your symptoms are worsened by the signal, you may not be one for whom the process provides relief..... and it is SO much better to learn it through the trial than to have gone through a radical implant procedure only to experience something unbearable. Best I can suggest is be in touch with your rep, because they surely should have given you their phone number so you could be in touch in case a TWEAK of the programs they gave you might provide that beneficial relief you had hoped for your trial. My rep gave me their numbers and I did talk to them during the trial. You might give that a go.
May all be well,
