Hi, I Fell In A Parking Lot About 3.5 Weeks

Hi, I fell in a parking lot about 3.5 weeks ago. My shin landed on the curb and all the brushing has faded, however all, of the pain of the bruses is still very much there. I can cringe with I put my weigh down on my knees. Is this something I should be seen for or just give it time? I have the exact same is sure with the hell of my hand that I also used to catch myself with know he fall.
