My implant which was one year ago this week for abdominal pain was done on an out patient basis at a surgery center connected to a hospital. In at six home before three. For me, the pain was extreme into week three, but I have never dealt with back pain only abdominal pains. My friend who had an scs implant a few months later called me at week two and said why didn't you tell me how painful this is? She had already had two very invasive spine surgeries. I told her I didn't want to worry her and didn't know how she reacts to pain. Long story short, lists of pain into week three.
Hoping you husband finds relief of pain and a successful outcome from his scs implant.
