I am waiting for the permanent implant to be fitted - probably at the end of January 2013. So I will post more information after it has happened.
The trial went pretty well. NO leg pain whatsoever (it was such a relief to not have sciatica for the 7 days of the trial - which in itself would have been beneficial). Also, back pain was reduced also - though not when constipated, as that sets off my back pain something chronic!!!! Sorry to be so gross, but I tell it, warts and all.
As for the sacro-iliac pain - unfortunately, it didn't do anything to relieve that horrible, stabbing butt pain, but I figure 2 out of 3 isn't so bad.
So I'm just waiting now to be called into hospital to have the Nevro permanently implanted. The device is charged up (every day) if necessary. If I'm going to use it 24/7, then it will need charging every day, which is no big deal as I usually have to lay down to rest my back and try to ease the pain anyway.
I'm currently still off work because, although I had the device and connector implanted on 3 December, I cannot believe how sore the site still is. I find bending down to do anything very uncomfortable and I'm just not fit enough to be at work right now. It seems the more operations I have, and the older I get, it takes its toll on my body and means my recovery is much slower these days. I figure this is a small price to pay if it works.
I may still need to be on the medication, but I'll see how things progress after it has been implanted for a while.
I live in South Yorkshire, in the UK, and as far as I know, the "Nevro" is under trial with the National Health Service. I actually emailed the Nevro Corporation in California (I think it is) and they gave me another surgeon's name and address of someone in Leeds who is also trialling this device. I have been seen by a neurosurgeon in Sheffield and I cannot fault the NHS so far. Their care of me has been outstanding, considering the budget constraints the NHS is under at the present time.
If any of you (in the UK) feel that you want to research with your own health professionals whether this device would be suitable for you or not, I would recommend you see your local GP as soon as possible for a referral to the relevant surgeon. Try and do it well before 1 April 2013 - as after this date, the NHS may be even more restricted in who they can treat.
Send me a PM if you want more detailed information about the 2 hospitals that I know of that currently see 'suitable candidates' for the NEVRO trial.
I'll let you know the final results after my final (I hope) spine surgery in January (fingers crossed).
Have a wonderful New Year to you all.
