I just did an update on long term outcomes for back pain surgery and we still aren't seeing large studies. The patients are there, but no one is doing follow up over a couple years. In the meantime, there are a great many home treatments that are available.
The little guy on the left is a TENS unit, every person with chronic pain's best friend (unless you have an inflammatory condition, in which case stay away). Clinicians can get these for about $45 and they run on a nine volt battery. I just don't see them being used instead of pain drugs, which is sad, because they are a much better option for specific pain.
