Hi. A couple of weeks ago I took a hit to my shin from my dog(he is a rather solid unit) It hurt like hell and left a very nasty tender bruise. It swelled up but that slowly went down over time. Now I m left with a very tender lump under my skin right on my shin bone. At times it has felt hot in the area. Just wondering what this lump could be. I m assuming it was the exact point of contact from my dog. Cheers Nicole.
