I used pain patches in the past, they worked great most of the time. I stopped because I didn't want to depend on them too much, I now use a natural approach (a very strong oil that numbs the affected areas very nicely). Best of luck with everything, Rose. Please keep us posted and sorry I couldn't give you more info on this; I didn't use the patches for too long. I'm sure someone else will be able to elaborate more on this tho, so don't worry
