Fell down concrete stairs and shin took force. very hard to weight bare very swollen & bruise coverings majority of shin. is it any major damage?

Time4ConcreteThinkin: In general, if it's difficult to bear weight then there may be more injury to the bone than a simple bruise and it would be best to have it examined and possibly x-rayed. If the x-ray is negative and you still cannot bear weight, they might decide to do another form of x-ray or put you on crutches, wait 7-10 days and then see you again and decide. Either way, probably best to see a doc for this.

A fracture: Is definitely something to rule out.if the shin took took most of force, a tendon injury is always a possibility.....ice, ice, ice, elevation and see doctor.
