Lidocaine
"I've been using Lidocaine patches for years now. Recently I became a Medicare patient and can no longer afford them.  
A friend of mine brought me some of hers. 
They were made by Mylan. 
1.  They would not stick unless I used paper tape to hold them down (this is a must if you have to use these). 2.  When I wore them on the inside of my knee they split into. 3. I did not receive any pain relief. 4.  These cost $100's if you do not have insurance. Medicare will Not pay. 
5.  Anyone that gives this product anything but a 1 must have stock in the company. 
The GOOD NEWS! 
While  I cannot afford them, I will tell  you I was using  same percentage but made by a company called Watson. These patches are over 1/8" thick gel/cloth back. These WORK!"
