bruise on leg causing knee pain

Posted by megsbox

I got a rather big bruise on the top of my quad muscle about a week ago. A bumb was instant after hitting my leg and then the brusie came up the next day.  I went swimming two days ago and after four one lap my knee began to pain after four laps I could not go on any longer.  It felt better the next morning then I spent the day on my feet going up and down stairs, by the end of the day it hurt just to bend my knee.  I am still experencing the same pain another day later.  Should I go and see a doctor or is there something I can do at home to help it feel better?
