Hi Lisa,
I agree with the others that it might be time to find a new doc who is willing to give you the full attention and treatment that you need!!

Before jumping ship, you may want to insist that he have a conference with you, so that he can hear you and listen clearly to your pleas for help, and to talk about the fact that the percocet may no longer be adequate..
If he is still unwilling to help you, then it might be time to find another doc who attends to you!
In the meantime, Mslday has some good suggestions for ways to reduce your pain and anxiety through breathing and relaxation...It does help!
don't give up, friend!
Many hugs,
hope4thebest
