Hi Teresa,   I had a neighbor that used this and since then has had two
serious back operations.   You have to understand that all this does is numb
the nerves which allows you to do things that may be making your back worse
and in his case,,,, much worse.
  If a person for some reason was unable to let today's medicine handle
their problem and they restricted their activities so as to not cause more
damage,,,,,,, pain relief is pain relief and people have to make their
choices.
     If you have RA, I hope you are seeing a Rheumatologist.   I would also
hope that you have discussed this with her/him.
IMO
