Welcome to the forum. I started a thread for you so others could also welcome you. Since your question was specific about the SCS trial I thought this would be a better way for you to get more information. There are many of us on here that have gone through the SCS trials and also have the SCS unit implanted.
I have a Boston Scientific and use it 24 hours a day. The trial was not that difficult. They do keep you awake so they can have your feedback when they place the leads in. You are sedated around the incision and it is not painful, at least my trial was not. They tape the wires onto your skin using what seems like an endless supply of tape. That is to keep the area where the wires are clean and it lowers the chance of infection. I was not allowed to shower or bathe during the week but I did use common sense and found a way to keep the area dry and still maintain hygiene. My experience was the trial did not work as well as the implanted unit. During the trial, I played with the unit to check out as much as I could. It takes some time getting used to the feeling that the electric shocks cause but I find the SCS helpful. It did not stop the use of others meds and I use the SCS and pain meds to handle the pain on a day to day basis. Everyone has their own experience and we all respond differently. If you have any further questions, don't hesitate to ask. We are here to help one another.
Please take a few moments and introduce yourself to those here, as we like to get to know one another. Blessings!
