I've discovered a marginally more useful way to use the marginally useful lidoderm patches. In the interest of spreading the word to others who might need this stuff (who turn up *everywhere*, someone at work asked about the patch on my hand, and it turned out that she has neuralgia in her feet. Her dr had suggested the patches but she hadn't tried them yet.)
My problem tendon runs down my thumb and along the side of my wrist. That's where it hurts, that's the most effective place to ice. I thought the obvious place for the lidocaine patch was along that side of the wrist. The patch actually works better when I lay it flat on the back of my wrist. I don't know if it's just making better contact for diffusion, or if the damaged nerve is a few cm from the tendon.
The best way to keep the patch on is with one of those self-stick elastic bandages. I cut it, so I don't have to wrap it 15 times around. But it's secure and easy to do with 1 hand (and it looks like a sprain, not a drug patch or a weird bandage for a cut. That's occasionally valuable.) Even with the elastic bandage, I can taste the lidocaine faster and more intensely when I put the patch on the back of my wrist than on the side. So there's definately better diffusion.
