Many thanks again to everyone! Dad had a follow up today with his doctor at the rad clinic. He was surprised that dad is not yet eating, but stated that everyone recovers differently. We did find out that alot of the pain he is experiencing is due to his lower denture. It appears to be irritating the gum area back by where his wisdom teeth were and this is probably causing alot of the pain. He was prescribed 2 different meds to help get the area healed and was instructed not to wear the lower set of his dentures.
Also, he is starting a new protein powder to be added to his 4 shakes a day. The doctor feels that when this mouth irritation is healed, he should be able to start eating again. He is getting some saliva back, as well, which is encouraging.
The doctor didn't seem too concerned with his weight loss. He wants him to continue his 4 shakes and also get a ProSure down. And continue his water intake. My dad goes no where without his trusty bottle of water!!! So hopefully soon, the mouth and throat pain will diminish and he can start on some real foods!!
