thank you so much. i have silver and dmso, but no bf&c. i plan to get a silver maker in a couple weeks. if i get a puppy, how will i know what the ppm will be or is there a gadget one can get to test that? should i spray on the silver and then rub on the dmso? and how often? the funny thing is, i have no idea what i did. it started hurting when i went to bed mon night and safter laying there fir 45 mon i had to get up it hurt so without even moving it.
