A guy of your dimensions with a sore foot/knee could compound your injury in just moving.If you are a college athlete, your sport-medicine department probably has a skilled coach who deals with players' injuries. If not, your regular doctor should be able to offer some advice. In the end, athletes of your size may need to consult an Orthopedist. Your regular doctor has to refer persons to professional specialists, so you are better off visiting your or your team's regular doctor for help.
Good Luck.
