"i had tried patches before and nothing stays on but about 4 yrs ago i tried salonpas which were ridiculously inexpensive so my expectations were extremely low and they stayed on until i took it off by choice over 6 hours later but they they contained no lidocaine ...within last month i heard they came out with lidocaine patches and rushed to get them ..only $8.00 for box of 5 or 6 and so happy i did they have come through again with low cost effective (more so than name brand) pain relieving product.."
