I have been using Lidocaine patches for about 3 years. You would be surprised how much they help. I always put them on the areas that are hurting the most and if you can calm them down then some of the referred pain goes with it.

I haven't noticed any side effects with them. You can use 3 at a time and it's 12 hours on and 12 off. I was able to quit using them for awhile but this lower pelvic/hip pain has made me have to wear one for the past few months again. I have worn them on my left chest area and I have finally got that pain calmed down unless I do something to get it going again.

They don't numb the area. The medication on the patch just goes into the skin.

Hope this helps.
