If you join (it's free) the microelectricitygermkiller  list at Yahoo,
you will learn how to make a device that seems to really handle localized
infections really, really well.  It's just a battery and a couple of wires
and is so very cheap and effective and easy, easy, easy to make.  The files
section of the list will tell exactly how others have used the device with
success so that will take care of the infection part.  Now for the pain.
When my mother had a herniated disc (osteoporosis), she said the only thing
that would make the pain bearable was to apply a 2 1/2 lb. therapeutic
magnet.  That was the only thing that would bring down the pain.  These
magnets are kinda expensive, but will outlast us by decades.   Best wishes,
pj
