Is there anything wrong with my knee?

be worried; but be proactive about knee health. of course it,s damaged. ice and elevate it as much as you can accept. take ibuprofen for swelling. if it hurts, there is swelling. do not exceed dosage amounts for any med you,re taking. if the pain is not significantly reduced in a week; you need to see an orthopedic surgeon. your family doc will just refer you. x rays will not show soft tissue damage. you only have two knees. there are no spares.
