Yes I have had it, and really dont want it again.. It used to wake me up (when i had finally managed to get to sleep) with a senstion I can only desribe as some one pouring boiling water into the veins in my lower arm - and no way of getting rid of it. Tubi- grip helped a bit, but not encouraged to be worn for too long, as it can exascerbate the problem. You will know whats causing it, because when you are doing that particular activity, it hurts more than it should do normally.Hope this helps!!!
