I dropped a 10-15 pound statue on my foot and its purple and hurts. could i have broken a bone?

Yes: If you are able to bear weight on the effected foot, it is probably not broken. If you cannot bear weight, I recommend seeking medical evaluation, including Xray to determine whether or not it is broken.

Foot Traums: You could have broken a bone, broken blood vessel or just badly bruised your foot. A broken bone is usually exhibited by sharp pain when touched, but don't rely on that 100%. Even if you can walk on the foot, it can still be broken. You should have it checked out by your doctor.

Possibly: With pain, swelling, and bruising I would get x-rays. The mechanism you describe could result in a fracture. Good luck
