A: I would start using one on each side of where you have the pain. I love this product. I have RA and it helps me a lot. As you use it you will be able to know if you need additional.

A: I use as many as 8 of the small patches in an area. There's no limit really. I have used them for years. They are amazing. Salonpas also are available in large patches. One has lidocaine. I use those on old surgery areas & my neck or shoulder.

A: They recommend just using one at a time, maybe the large one, but more or leaving them on past the eight hour time doesn't seem to be a problem. They helped my back and knee quite a bit for a while but it seems to eventually lose its effect over a lot of use. The lidocaine is very good but difficult to put on by oneself.

A: When using Salonpas Pain Relieving Patch 60ct up to 4 patches can be used at the same time.

A: No, this item doesn't contain latex.
