Kris had terrible ear pain which radiated down his face. This was the symptom that initially sent him to our GP. It got worse and worse. It wasn't constant, some days were worse than others. In his case it was from the lymph node pressing on a nerve. This pain went completely away early on in treatment.
Insist on some good strong pain killers for your Husband. There is no need to be in pain.
Hope this gets sorted .
