I'm so very sorry for your loss, jynier. Being no stranger to bereavement I know that tiime doesn't heal but its passing does enable us to reach some accomodation with our grief whereby we muddle along in much the same way as we always did, albeit that we are irrevocably changed in ways that words cannot fully describe. I must confess those who ask 'are you feeling better now?', as if you've had the common cold, narrowly escape being punched in the mouth given a verbal lambasting 
My new sooper-dooper 'walking aids' were put through their paces Friday before last when I went out for drinks at a ritzy hotel bar and they didn't look out of place. In fact, they attracted sufficient admiration to cause more than several one drink to be sent over to me 'with compliments'.
That same night I experienced a Life of Brian 'It's a miracle moment' in which I was able to walk to the powder room and back unaided. I felt quite the fraud as I sauntered through the bar but, unfortunately, the power of whisky sour soon evaporated and it was a very different story the next day.
I've kind of superceded the pain barrier and have dispensed with the heavy duty pain killers unless the discomfort has been so intrusive that popping a couple is absolutely necessary. If only I could just stay ratarsed inebriated and float above it...
I'm necking krill oil, glucosamine/chondroitin, collagen, calcium, zinc, vitamin d, and greenlipped mussel capsules like there's no tomorrow and one/other/all does seem to ease this condition, albeit that it could simply be that I've got used to it and have become accustomed to the limitations its placed on my ability to function 'normally'. How did similarly afflicted souls cope before the advent of online shopping?
My highy paid quack (no offence intended to cafecito) in London is adamant that it's replacement or nowt. However, my pa and our family doc are researching the success rate of stem cell treatment and this may be a non-surgical option which I'll try before giving further thought to 'going under the knife' or, rather, the Black & Decker.
I did resolve not to use this space to bang on about the joy of osteoarthritis but, by god, I need a place to vent so it's a mea culpa from me and my best wishes for a good night to all of you.
