About 5 minutes ago, I hit my foot really hard on my bed post. It hurt badly, but I just shook it off. 2 minutes ago when I went to the bathroom, my foot hurt with every step I took near the front area (right foot). It's about a 7 on a 1-10 scale of pain. Is it broken, or is it normal after hitting your foot hard on a bedpost? Should I have it checked out in the ER?
