Intercoastal

So I went through a Huge scare with the doctor telling me that my gallbladder might of gone bad but after many tests and lots of stress that we found out I'm having intercoastal pain. My doctor couldn't go into more detail because he wasn't sure about how to find out, and said I would have to go to a specialist to find out more. From the symptoms I would say it has to do with the nerves but I'm not doctor. I've been on prednisone for the past month and it has helped and as of today I have stopped so we will see what happens. One of the biggest problems that I have faced this past month is lack of sleep. I am a side sleeper, but with the intercoastal pain it is almost impossible. From my reading this is a normal part of it. I also have arthritis in my lower back so when I "try" to sleep I wake up with my back screaming at me. I also hate the feeling with so many pillows under neath me. This lack of sleep has really gotten me down, can anyone give some advice or share their story with this disorder? Is there any other good forums/chat rooms/support groups online?
