I understand what you are talking about but mine is transient. It isn't always in the same place so I am usually in for a surprise when it happens. Unfortunately, I haven't figured out what to do about it yet or what works to help it. I'm hoping others can chime in and be more helpful but I just wanted to let you know that you are not alone.
Hi Leanne: I have the same thing, only it's my neck and upper back. I've been trying IcyHot, it comes in an antiperspirant-like stick, and it's not perfect but I do get some relief from the pain. And I smell minty! LOL Lou
