Last Sunday I got attacked by a dog. Mainly scratches that broke the skin, two on my arm and one in my lower abdomen . The one on my ab was not deep at all, very little to no bleeding however it is a huge bruise . I went to the urgent care that same day and was treated with a tetnis shot, bandaged and antibiotics , butI now I have a hard lump in that area, it doesn t hurt but what could it be?
