Re: bump left from broken toe?
I stubbed my pinky toe years ago, I believe it was broken although I didn't seek medical attention, either. For 1 week, I was limping, for 5 weeks, it was sore, for several years I could feel a... bump, or thickening, in the bone, but it's gone now.
Of course, I was only 13 at the time, and bones heal easier in kids.
I think any broken bone will leave a bone scar.
