Sabja, please let us know what your surgeon said at your appt. I wonder if some of your mouth sores might be a result of the Erbitux [did you have the rash side effect while taking it?] Also, good oral hygene is often very hard to maintain during and after tx. and that leads to more mouth sores. Hope you got some good info from your visit on the 26th. Amy in the Ozarks.
