Call your doctor to up the pain meds. It could be an infection but my guess its probably from the cancer. My mother suffers with sever pain in her ear also and its from the cancer. I had the call her doctor because she was taking Norco but it wasn't strong enough. Her doctor ordered Oxycotin along with the Norco. Also you can ask for the pain patch that may help you also.

As for the flem I know that is horrible also. It's also bad with my mom to. You can rinse your mouth with baking soda & salt or there is a prescription called Magic Mouth Wash. Call your doctor to order that if you don't have it yet. Nothing really makes it go away but you get some relief.

Get well soon and stay positive
