Aargh knee keeps giving way and jarring. Can't walk downstairs...

...and I'm a teacher. Not working today, but am meant to be tomorrow. I do lots of charging round and rushing up and down stairs, not sure what to do.

It hurts and keeps giving way, especially on stairs. I'm normally carrying a laptop, mark book, cup of coffee and general detritus up and down stairs at top speed at work. What's wrong with it?

Could be patella problem maybe? I had that and it was the patella moving of its track. Had to have a lateral release done to cure it.

off, not of (of course).
