May I ask why you turn the SCS off at night? I too have an Abbott, the Eterna model, and I have it one, aside from medical exams, surgery, security. Your ailments mirror mine, I have the laundry list as you do, including the spinal fusion in 2014. The device is working, and I don't have the pain the AM when rising, and I am not concerned a disc will slip when I am engaged in sports, pre-SCS, as it did in 2022.
The pain management doctor mentioned to me if it was removed, I would be back in square 1 again. For now, and it has nearly been 1.5 years with the SCS, and I am able to participate in the sports I love, without the worry how I will feel later that day or the next morning,, with pain.
However, I am curious why you shut it off at night?
