How Topical Lidocaine works on Arthritis:
Lidocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.

The American Pain Society reported that Lidoderm patch containing lidocaine results in at least 30% improvement in knee pain on those patients suffering from knee osteoarthritis. The Lidoderm patch used in the study was used once daily for 12 weeks.
