I have used the pain patches for about 3 years now. They work. If you have shoulder pain, use one or 2 patched. If your back hurts, apply one or 2 patches. Knee hurt, you bet, apply where it hurts. The pain is either diminishing to the point you forget about it, or it is gone.
I have purchased the sleep patches. I placed them in several areas and couldn't get them to work for me. I retired from a swing shift job, probably had a lot to do with it.
The pain patch is the best of what I have...
