Hi Caco, bad to hear about your dad's suspected mets.

Unfortunately, it is almost similar to my dad as well. His tongue sore refuses to go, he has a bulge and continues to have pain around his right jaw and under right ear.

I was at hospital last weekend, RO have given him some serious pain killers and something to reduce the swelling. I am just waiting for 13th Dec when he'll have PET/MRI. RO has refused to do biopsy before end of three months so pretty much wait and watch!

My dad is low due to the suspected mets, so I can probably understand your dad's situation as well. Take care of your dad and ask him if he wants to meet and greet people.
