Thanks for all the advice and support.
I don't know why I was expecting a final answer today: I should've known better really.
We spoke to a young female doctor who openly admitted that neurology is not a field that she knows much about. She told me the neurologist had been to see dad last night and given him the results of some of the tests, as follows:
MRI came back clear
EMG showed muscle wastage, due to nerve damage throughout the body but focusing mainly in the legs and arms at the moment. There is no 'outward' reason for this, e.g. trapped nerve, so it is a 'condition' that has cause this rather than an outward reason of some sort.
CT scan was mostly ok, BUT it picked up an abnormality at the base of his oesophagus going into his stomach. It has expanded the base of his throat but they don't know whether this is an obstruction or a swelling, so they plan on doing a scope with a camera down his throat tomorrow.
God only knows what that is, then...
But what the female doc did say was the the neurologist has not even mentioned the poss of MND to her which she would have expected him to if this was a suspicion, which is rather surprising...?? But I'm not holding my breath; I know this could be an oversight and it doesn't mean that it's not that.
anyway, if they don't get any more answers in the next few days they will be sending him to Birmingham QE where they have an excellent neurology dept. Hopefully he can have tests there and then come back here, as this will be a nightmare for visiting him, what with the dds to look after and sort out, etc.
I am ringing the neurologist tomorrow in the hope I can meet with him on Thursday when he's next in to our hospital.
so no real answers yet, again...
