Thank you for your query at DoctorSpring.com
I have read your query with diligence .
It looks from your detail that you may have A march fracture in your foot .The pain and the bruise issue may be due to this.You should have an X-Ray of foot to rule out this stress fracture in your foot.At this time I will advice to avoid heavy activities & keep your limb elevated on a pillow to have relief.This may need a supportive cast or splint for relief on confirmation.
Hope this was helpful,
Feel free to discuss further,
Hope his will help you.

Thank you for your response! A stress fracture does make sense I suppose. Today it is slightly tender if I press on the top of my foot, but does not hurt to walk on at all. Is this typical of a stress fracture?
Yes,sometime presentation is with less pain.x ray will be helpful specially within next 2weeks.Within this duration it may show callus or healing bone.
With best wishes.
