On that picture is a second nerve exiting the groin, called the femoral nerve. Place the other half of the patch over that area.

In other words, because people have different anatomies, you might have the nerve not exactly in the place shown on the photo. Place the 2 halves of the patch next to each other, in that area to assure you hit the nerve spot. I put mine more on the thigh part, and not the lower abdomen, because the thick ligament may be a barrier for the drug to penetrate.

The nerve goes UNDER that ligament and exits into the thigh.
Where is comes out, is where you put the patch. If you put the patch too high up into the abdomen, the ligament may be in the way.

I know it sounds complicated, but once you do it, it will be easier.

Also make sure you do not have lotion or oils on your skin, or the adhesive may not stick. Lidoderms are trickey. You may have to use tape to make sure they do not move around, if there is any sweating present too. That is just the way they have been made.

On this picture the red areas are marked for the patches.
(ignore the green area-- as that is something else)
