My wife woke up today with a "black eye" with no apparent reason. It is dark red and it starts right under the corner of her left eye and follows the lower orb shape. It is more or less the size of a dime (smaller) . There is no pain or any other symptoms. Her blood pressure is normal 117 over 84. Her Medications are Synthroid, Lipetor, Paxil, Zyrtec. She is 64 yrs. old and generally healthy. Is there anything we can do? Should we be concerned?
