I have a 760 lb. steer calf w/ swelling in his brisket,where the 2 folds in the skin begin. the top portion is the size of a good fist and bottom fold is a little smaller. it is not real hard or squishy,warm to the touch and very sensitive to him. Good temp, eating good, no punctures or drainage,he is stalled alone.Nothing in the stall to have injured him. Hope someone has an opinion. thank you
