falling down

Such a long time since i had a blue black... Yesterday there was guides activity, i fell down while running and my hips hit the edge of the step and my knees hit the lower step. It hurt terribly. And there's a stretch of blue black mark left on my hips, about 5 cm long. A bit of red at the part where the impact was greatest. My knees were red when i just fell and i realised there were blue black marks forming at the knees as well when i reached home. It had been horrible at night. Every time i shifted position in bed, the slight movement would cause pain at my hips and the knees. The previous time i had a blue black was like years ago, when i was still in lower primary. I rolled down the stairs in my house twice, from 3rd to 2nd floor then from 2nd to 1st. I remember that i felt very giddy. But there were only blue black marks, no blood. I was perfectly fine and i didn't even visit the clinic. But i fell asleep soon after so i didn't feel much pain. But this time it seems worse. It's still a bit red and when i touched the affected part slightly harder, it hurts.
