Bad bruise on leg..WORRIED?

I fell out the shower about a week ago. I know you guys are probably wondering how did you fall out the shower, I was light headed and got really dizzy. I have one of those stand up showers I fell through the door and onto the floor I have ceramic tile in the bathroom. Anywho, I hit my head and scraped my knee and managed to bruise my thigh some way. Later that night I noticed the side of my thigh was swollen really bad over the next couple of days it got worse it was greenish/purple. I started to put ice and used a heating pad on it, it hurt really bad when I would put pressure on it. Now a week later it hurts somewhat but not like it did some of the color has gone away..its no longer gross looking its a darkish red color. I'm worried because when I touch it its really hard bump. Any idea what that might be? I assumed it was a calcified bruise should I see a doctor or wait it out like I've been doing..
