Knee Injury - DRATS!

Not sure how badly I'm hurt... My right knee miniscus (outside) popped twice during training yesterday leaving slight dull achy pain. Got pushed over at an odd angle. I continued to roll, but baby'd it quite a bit. No pain after workout and it didn't hurt at all yesterday afternoon/evening, but something didn't feel quite right. I woke up this morning with moderate pain and a general feeling of instability. Can't post on the leg and turn or do squates without pain. Never had a serious knee injury before so I have no way of knowing if this is something that will resolve itself with a week or two rest or if I've really done some damage. . . Fingers crossed.
