I Fell 3 Weeks Ago- Hitting My Shin On A

I fell 3 weeks ago- hitting my shin on a wooden step. It hurt but didn't break the skin or bruise. The pain now is about a 1 as long as I don't touch it. The problem is that if I bump it or push on it, the pain shoots up to 10+. I had an xray done this past Monday but they said it's not broken- just a bad sprain. Should I get a second opinion or could it be a sprain?
