Suggest Remedy For Pain In Tailbone, Weak And Heavy Legs

Hi,I hit hard my tailbone 10 hours ago, i almost did not sleep last night, I can walk around the house, but my legs are a little weak and kind of heavy. Should I rest or could I try to take a slow walk outside, since I can't really do much with the pain in my tailbone and around it? I'm concern about the strange feeling in my legs. I still can move them and feel, just that weakness... Could it be just from the bruised (hope not broken) tailbone? Thank you, Julia
