Oh dear, backless! I'm so sorry this is happening to you! I hate how those of us in pain have to live in constant terror that they will take away our only comfort at any moment. With all this frenzy lately with the overdose epidemic, I worry all the time that they will clamp down so hard that none of us will ever receive any relief again.
I don't have any good advice for you, but I hope that you can get this worked out one way or another. At least know that there are people here who get it.
