My dog was running quite fast, and I stuck my leg out in front of her to stop her. She rammed her head into my shin. I immediately got bruise where she hit, and soon after, a goose egg came up. about 30 minutes later, the goose egge tripled in size. I am elevating my leg with an ice pack on the goose egg. the swelling is not going down at all, but it is not getting bigger. Do I need to go to the doctor? 36 years old, excellent health.....
