"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.
