My daughter felt something solid while swimming on a North Carolina beach this morning (July 25) and now has a raised welt about 2.5 x 4 cm with a somewhat larger reddish area around it. It is mildly painful. There are no visible foreign bodies, stingers, etc. What could it be? She doesn't seem to be having any severe symptoms that would require an emergency room visit.
