I had my St Jude SCS implanted in July 2013. In Sept 2013 I had revision surgery due to a fault in the system - turned out to be a faulty lead. Since then it has worked ok. Some issues with coverage but, with additional scarring in it has improved quite a bit since the early days. My electrodes were implanted at T9 via laminectomy for stability purposes because leads moved too easily during the trial and my control unit is in my lower right hand side abdomen.
Tonight, after having the stim turned off for a couple hours, I turned it back on and the first sensation I felt was a stinging sensation at T9. It's definitely coming from inside because, since the surgery to implant the leads, I have had no feeling in that part of my back. This is something I have never had before. I have also been getting a range of error messages on the control unit over the last few weeks (eg: 26 FD, 36 FD).
Have an appointment next Wednesday to have the error messages checked out and to do some reprogramming so will talk to St Jude Rep then about this new stinging sensation.
Just wondering if anyone else has experienced anything like this.
