I Knew Back In The Days When I Was Young

I knew back in the days when I was young that meth would numb nerves in your teeth and get rid of all tooth pain...better then anything else I have nerve damage in my back cause I have ankolosis spondalitos...and inflamation...I had started to wonder if that would help the nerves in my back that would help to stop my bones from growing together...trying to figure out what the best thing is for this...I also shoot hoops...it tends to feel 10 times better when im threw...is that a good thing to do...and when my bones chip of into my muscles and such will they stay or disenigrate...please reach me back on this...and would a rife machine be good to have for this also...
