Perhaps the radiation has caused swelling inside his throat which would mimic choking. Has anyone scoped him ? Predisone would reduce swelling and are very small pills. Or even a couple sessions with a Nebulizer (similar to the inhalers asthmatics use).
Sadly you often have to be quite demanding as the radiation doc and most of the team focus on the cancer not these quality of life issues
Sorry to hear he is having such a hard time. Christine's time line is excellent and reliable. The neck dissection is brutal. My neck felt like petrified wood, literally. I would reconsider pain pills as it made the strenuous PT easier. Pain is not good for healing.
Feeling strangled is not normal, so keep pushing for help. Sometimes Ativan helps reduce unconscious muscle clenching. Just throwing out med ideas.
