Pain
"I had tried Lidoderm and had fair to good results.  I was reluctant to try the Flector because of the cost.  My insurance did not cover them.   In an impulsive act due to frustration with pain, I got the script filled.  Within 2 hours I noticed that the severe pain in my knee was almost gone, and I slept very well through the night.  These are a miracle and work as well as or better than any systemic medicine including narcotics.  They really do work.  "
