Try cayenne, it's great for inflammation and pain. I use it on fasts instead of pain relievers.  Actually I use it even when not on fasts, it's a staple in my home.

Here's an excellent article (part I and II) on cayenne and it's healing benefits: http://curezone.com/blogs/m.asp?f=573&i=89 

I drink it in OJ or in hot lemon tea.  Sometimes I just throw half a teaspoon in a mug, then add a couple swallows of warm or tepid water and throw it back like a shot of tequila and chase it with more warmish water.  When I do it that way, it's for some serious pain, headache or otherwise.  If there is no relief within a half hour, then I do it again.  Usually it works right away.

Enemas are also excellent when pain or severe detox occurs.  They, much of the time, bring instant relief.  Sometimes lower back pain is a result of impacted fecal matter.  Give it a try.

I hope you feel better.  You've come a long way.  I hope you make it to the finish line.

Best to you,
