A relative (72?) fell backwards on Monday ,hitting the back of her head on the blacktop. She did not get knocked out, but had a headache. She went to the E room at the hospital, had some tests and has been sent home (to rest) til next Monday when she is supposed to return to the hospital for more tests. Today, Friday, she woke up with the left eye ball drooping. What could be wrong? ( All this in 5 days )
