[carambola]

I am a random poster, usually offering help. I need a little help.
I'm not due for insurance until March but i popped something in my knee.
For the first few days, i didn't feel pain, just discomfort. now that i can localize the pain it seems to come over the knee and descend into the fibula. I figure i am riding this until then. Are there any exercises i can do to preserve the cartilage.
Sorry to impose.
