Don’t work at all
I have used many different types of lidocaine/numbing patches for the nerve pain I have emanating from my spine. All other patches have worked somewhat. These did not work at all. Moreover, something about the stretchiness of the fabric made my skin itch.<br /><br />I put the pain bloc patch on immediately after removing a ZTlido patch that had been on for 24 hours. First thing: the pain bloc patch didn’t stick in all places. Second thing: my neck started hurting after about 20 minutes (when the ZTlido patch would have completely worn off). It kept hurting more and more as the four hours wore on. By the end of 4 hours, I couldn’t stand it any longer. I was in pain, and the weird itching sensation was driving me batty. I took the patch off. All lidocaine patches make my skin numb to the touch. I touched my neck where the patch had been. I could feel everything, even light touch. No numbness whatsoever. The itching stopped immediately upon removing the thing, thank God.<br /><br />I really wanted to like these, but they seem useless. I highly recommend trying a different brand. Who cares if they stay on if they don’t numb anything?
