I'm up because I'm a night owl and often mumsnet work late into the night, skype with my folks in the States, other relatives down under, and assorted friends around the globe, while London sleeps. However, tonight I'm waiting for painkillers to kick in and ease my troubled knee so I can hobble up the wooden stairs to Bedfordshire.
I'm slowly getting my brain round the unpalatable fact that a replacement may be required. If all of the various potions and alternative remedies I'm necking don't do the business, I'll be booking a flight home and checking in for surgery in the not too distant future.
At this rate I might be temporarily leaving the UK on squeaky's return plane, presupposing that she decides to come back 
PS anyone know of a miracle cure for osteoarthritis of the knee? Or even half a cure?
