My mom just had a trial stimulator inserted 3 days ago. While it has helped with (upper) back pain (she's had 5 back surgeries), she is telling me she just feels strange. She said that she's not sure if she can handle it mentally. Has anyone else felt like this? She's supposed to go back to the doctor in 2 more days, but I told her to call them now and ask if this is typical/normal. She has suffered so much. Lower back problems eventually led to getting two rods in her back, like when you have scoliosis. Now it's the upper back that hurts.
