I have all the symptoms of a hairline tibia fracture after my 92# dog ran into me. localized pain with a burning sensation also a little discomfort when walking. should i seek medical treatment?

If you think the encounter broke your leg you should get evaluated. Since you did not post the symptoms involved, it is not possible to decide if they truly suggest a fracture or any other injury in need of urgent care. I would contact your docs office and discuss the symptoms with them for guidance.

If you able to wear weight on the foot on that side and can walk, even if with some discomfort, you may watch and wait. Reduce weight bearing exercise/activities for about 3 -weeks. If your symptoms are worse than that I described, it would be prudent to see a doctor. Wish you good health!
