hi there, looks like you have injured the soft tissue
of your arch of the foot which is causing the pain,bruise
and swelling. You can continue putting ice and keep it in an elevated positition as long as possible and take chymotripsin and anti-inflammatory tablets. It should start getting better in 4-5 days but if the symptoms continue or swelling increases then visit the ER and let them take an x-ray and consult the doctor. Hopefully it will be fine in a few days , take care.
