pain
"I have CHRONIC sacroiliac joint and coccyx pain that does not show up on MRI or X-ray and I've used this patch for a little over 1 month with NO side effects whatsoever.  I do notice that it takes about 2 to 3 days to feel the "full effect" of the medication and I do notice the increase in pain if I skip a day.  Maximum pain for me WITH the patch is about a 2 and that's great."
