Does Foot Healing After Being Stepped On By Horse Cause Pain And Swelling?

Hi,
I'm 29 years old female. A week ago a horse stepped on my foot. It was very sore the first day, but my foot was only a little bit swollen. The second day the bruise started appearing. I applied some aloe vera gel on my foot and in the evening voltarol gel. I took some nurofen as well. Last night I woke up few times because of the pain, and since yesterday I'm limping, as putting any weight on the foot is very painful. Could you please let me know, what you think could have happend to my foot? Is the healing process so painful? Day after the incident I was riding the horse again, I thought I was ok. Now I can hardly walk.
