Welcome @noaz, I can't begin to imagine how difficult it must be for you to deal with the pain. It's good that you have found that ice and a TENSunit helps some but it's good to keep searching for answers and learning as much as you can about the condtion. I did find this article that sounds like it could be an answer for something to learn about if it works.
