Pain
"I use these patches on my neck due to nerve and muscle issues. They don&#039;t work as an anti-inflammatory. However, they do help with the main caused by my inflamed muscles. I sometimes get tingling in my face and hands and arms that get pretty severe, and these patches relieve most of the pain and/or numbness within 15 minutes. They do, unfortunately, seem to never want to stay on for more than an hour."
