These patches felt warm on my feet. I slept and all cramps were gone within 20 minutes. No more horrible pain the entire night and since 3 days ago. Just ordered more. Cut the top of my socks to loosen to cover after patches put on. So blessed and thankful for this relief.
I have suffered from chronic back and shoulder pain for years, like so many people who work at a computer all day. (It will kill you.) Naturally I've tried everything, including the lidocaine. I haven't had much luck with them. But these ginger patches are great! They actually work on my pain in muscles and joints. Definitely worth trying out for any kind of muscle pain.
I bought it to treat my swelling feet. I just stick the patch under my feet when I go to sleep. It takes 5 days to work. No hassle no pain, easy treatment.
