I fell on the side walk on my knee should I go to er to be safe ?

Is it swollen? Can you walk normally? Do you have full range of motion? I would avoid ERs and all the sick people unless you're having a lot of issues with it. I would ice it asap.

What they said. Reserve emergency rooms for actual emergencies. Too many times are they being taken advantage of.

I think you should call your ob. Maybe you can be seen there.
