It appears we might be talking at cross-purposes. I was talking of nibbana, not vinnananirodha.
To differentiate the two, I understand nibbana as what the Buddha experienced from the time of his enlightenment to the time of his death (and I shant speculate beyond that). Vinnananirodha was a temporary state, induced through meditation, which acted as a painkiller.
Physical sensations are not dependent upon avijja... hence, the Buddha could still experience them.
