My 80 year old mother fell before Christmas and hit her head on the curb outside. She had bruising around her forehead and eye. She seemed fine, but in January had a strange episode with sudden onset nausea, dizziness and feeling faint. After a check up in the ER, they said it was the flu (which resolved within about 5 hours). She has seemed fine since, until today when she experienced lights flashing in her left eye and hooded vision. She saw an opthalmologist who indicated she does not have a detached retina. They are considering an eye stroke but i am concerned that this may be related to her fall and potential brain injury.
