husband got hit by a baseball in the side of the neck and now has pain in the opposite side jaw and upper shoulder area. He did bite his tongue close to jaw linewhen it happened, so that could account for jaw pain, no pain or bruising at impact site, however. I ve read that we might be concerned about restricted flow due to possible injury to blood vessels, but no other symptoms other than what I ve described. Are there any immediate concerns?
