Well we still have not had the results back from my fathers biopsy, he is in a lot of pain and cannot swallow his saliva. We are planning on taking him to ER as he has not been able to eat for 2 days now. Does anyone have any suggestions how to keep him comfortable? I mentioned in my earlier message about First Mouthwash but neither his doctor or the ENT will prescribe this until we get the results back from the pathologist on his biopsy. We are worried about him as he has not even started treatment but is unable to swallow....
