Well, I am sufficiently recovered from my dicky knee to accept Petite Soeur's invitation to walk in the Mother's Day Classic again this year. After all the treatments I endured:
acupuncture
boring exercises
painful physiotherapy
drugs
shark cartilege tablets
rest
fish at every meal
etc.
it is impossible to know which one did the trick so I am perservering with all of them except, for the time being, the physio which is expensive as well as painful.
I checked my collection of remedies and found only one is from the dodgy pharmaceutical lab - Heaven knows what's in it - it's like buying a chiko roll at the football.
