Nellie that might explain the trail of wee pieces of black, plasticy, rubbery stuff that I keep finding on the floor. I must apologise to DH's zimmer which has been getting the blame 
Two pieces of good news yesterday. First, while searching under the bed and the wardrobe to find Granpal's summer sandals, I twice came across the single, size 5 wellie that I have kept, hoping its mate would turn up. Took a while to dawn on me that I had seen it in two different boxes - et voila - I now have a pair which I will present to my neighbours for their newly walking 1yo DGS 
The Biggie however is that after all the angst, the Specialist at re-hab had a talk with DH and told him that she had ruled out Post-Polio Sequelea (I can say it out loud now) as a diagnosis because of the improvement in mobility and muscle tone that DH has achieved over the past month or so, which would not have been possible if he had PPS. Whoopee! They now think his condition was down to trauma and enforced inactivity. And wouldn't you know it - DH has been keeping to himself (didn't want to worry me) the fact that the Physio suggested PPS as a likely cause of his problems 2 months ago and it was this that spurred him on to prove her wrong. WTF 
Feel like a celebration but planned trip with DGC to the Famous Alva Games is currently on hold as there has been steady rain all morning which looks set to continue.
