Sounds like: you are suffering from a mild concussion! You certainly should have an EYE exam (detached retina is often under-diagnosed!) Headache and photophobia can last for quite a while. Get a check by your Primary Care Doc...and if Sx continue a NEUROLOGIST! Good luck! Hope this helps! Dr Z

Go to Doctor: You could have a serious head injury. Go now!
