Should I go to highschool tommorow on a dislocated knee? I can hardly walk on it and won't all the walking damage it even more?

Do you have. Crutches? How do you know it is dislocated? If it is and you sought care they should have given you instructions including if it is safe to bear weight and how to care for it and when to follow up. If you are guessing you should seek care as permanent damage can be done to your knee if not taken care of properly!
