Could he have MS?

 So Geoff's been fine for the whole of January, no funny turns, no itching, and I've been sleeping back in bed with him since having gone to Mexico about. He's really much better just weak. Today he said he thinks he might be getting MS. I don't think so, but he said well he has numbness in his feet and lower legs and now his hands are starting to feel numb. I said it's probably lack of exercise.
