Boy, I have no idea if there would be a problem with recharging the battery over the lidoderm patch. I know when I recharge there is always clothing between so I would think that as long as the patch is not too thick it would work. (I have never used a lidoderm patch so I don't know what they look like.) It might take longer to charge that way because you wouldn't get as many bars but if it's the only way you can get comfortable in recharging, I personally would do it.

Good luck and let us know if it works!!
