My 19 year old daughter returned today from a long, holiday weekend (4 days) of fun in the sun at the beach house of a friend, complaining that she s had a non-stop headache for 3 days and that the fingers of her left hand have been tingling for 3 days. She had a fever at least one of those days (determined by touch, not thermometer), but does not have one this evening. She ordinarily wears glasses for mild/moderate myopia but wasn t wearing them for the 3 days she was at the beach. Her summer job, which she was last at the day before she left home, involves teaching tennis to children 5 - 10 years old. She is otherwise in good health and very athletic.
