My 8 year old had what they thought was pink eye a couple weeks ago. It was treated with an eye ointment, and when the treatment was complete she started complaining of bad headaches, a few times a day. Then, a couple days ago she told me she'd been seeing small black spots, that move, most of the time, but not all of the time. Today she said her eyes hurt - she described it as an ache. Then, tonight she told me when she closes her eyes, it feels like her eye lids are pounding.(it hurts). What could this be?
