Hi, a tress branch fell on my wife's head on 1-oct'2014 - she gets a severe headache while trying to read or watch tv or operate a smart phone.

Two months??: Could be a residual injury to her neck or some sort of concussion symptoms that are still present. Did she go to the hospital or see a Dr. after the accident? I would go see a Dr. and have testing done.

Need more info: Was she evaluated by a physician and had a head CT scan ? If not, then please get her evaluated first. I hope that she gets better soon !
