dead leg injury need advice please

Options
Hi I have a major dead leg through somebody kneeing me in the thigh, I can hardly walk.

There is no swelling or bruise,but the pain is intense, its been over 5 days now. Ive tried applying an ice pack each night for 20 mins here and there, I have strapped it up with a compression bandage.

How long can I expect to be out of action? does anyone have information or advice on this sort of injury?
