Is there a pain patch that works in a localized area only?

Many years ago, I broke my right toe, in fact nearly severed it from my foot. A very heavy piece of steel I was moving fell on it, and the flanged end cut nearly through it. I was in Corfu, Greece at the time and am not sure I get the best of medical care setting the bone. It now aches constantly. Doc says there is just some localized arthritis that’s settled into the damaged joint in it.

So is there some sort of pain patch you can put in one spot that doesn’t affect your whole body but treats the pain in that one area? I don’t want to take heavy-duty painkillers to knock this pain down. I know from experience with an abscessed tooth that even taking two 10/350 Vicodins (that’s 20mg of hydrocodone!) doesn’t stop the danged thing from hurting.
