This stuff is incredible. I woke up with a really terrible neck ache one morning. It was hard to function all day and was so painful and irritating. At night I recalled that I had this balm and my husband gave me a neck massage with it. Within minutes the pain was gone. I couldn't believe how well it worked and it lasted for hours! My only regret was not having used it earlier in the day. I will always have this in my medicine cabinet now.
