I spoke with an RN on Friday. She said she had the Abbott DRG implanted about year and a half ago by a Dr.Pavli Damian in New Jersey. She is very happy with the result. She highly recommends it. She said there is very little parathesia, She has another SCS implanted on the other side. So, she has two of them from different companies. She had 2 foot surgeries and an auto accident before the implants. She claims she doesn't notice the implants and she has at least 90%or more of pain reduction. However, she can't even be around the MRI machine at the hospital where she works Fearing it would turn off or interfere with the DRG implant. She said a CT scan would suffice and should be used instead of an MRI if you need one
