I bruised the bones in my foot about 2 years ago. Was down for 4 weeks, had to take a leave of absence from work for it. Honestly, still hurt badly for another 2-3 months after that. Today still aches after a days work. As mentioned above I now have a big knot on my foot where it happened.
I had a severe case... numerous bones in my right foot right under tendons attached to my ankle. Those tendons rub against the lump there and I still have days it's hard to stand for long. As I understand it, you could just end up with some discomfort for a bit, or it could be a long term ordeal. Just depends on the severity of it. Hope you feel better soon.
