Rosie,

As MrsD said, the pain in your foot may be referring from another area...like the knee. Keep in mind that much of pain from PN comes from the spine, so applying the patch in different locations (including the lower back) may be helpful.

Also, have you seen a podiatrist? I have PN in my feet but new pain on top of my right foot was getting bad and seemed uncharacteristic of PN. But I wasn't sure, so went to a podiatrist. After simple xrays in the office, it appears my entire foot is collapsing...literally. So, if you are not sure what is causing your pain, or the patches don't help even when placed in various locations, consider seeing a podiatrist. It might be something different, all together. Just a thought.
